The device integrates both high-side and low-side MOSFETs, requiring only an inductor and a few passive components for a complete step-down regulator solution. The 2.1MHz fixed switching frequency enables the use of small external inductors and capacitors, minimizing total solution size. Internal soft-start limits inrush current during startup, and internal compensation simplifies design by eliminating external compensation components. The TPS560430 is available in two pin-compatible versions: the PFM version (TPS560430x) enters a pulse-frequency-modulation mode at light loads for high efficiency, while the FPWM version (TPS560430x2xx) maintains forced PWM operation across the entire load range for tighter output voltage regulation. The reference voltage of 0.6V with +\/-0.5% accuracy (at room temperature) provides precise output voltage setting through a resistor divider. Protection features include cycle-by-cycle current limiting, hiccup-mode short-circuit protection (which reduces average power dissipation during sustained faults), and thermal shutdown with automatic recovery. The minimum on-time of 60ns supports high step-down ratios even at the 2.1MHz switching frequency. Housed in a tiny SOT-23-6 package, the TPS560430 occupies minimal board space for space-constrained applications.","working_principle":"The TPS560430YFDBVR operates as a fixed-frequency peak current-mode synchronous buck converter. Key subsystems include: (1) Peak Current Mode Control - the high-side MOSFET current is sensed and compared with the error amplifier output; when peak current reaches the reference level, the high-side switch turns off and the low-side synchronous rectifier turns on; this provides inherent cycle-by-cycle current limiting and simplified loop compensation; (2) Integrated Power Stage - the high-side NMOS switch and low-side NMOS synchronous rectifier are integrated on-chip; the bootstrap capacitor (connected between BOOT and SW pins) provides the gate drive voltage for the high-side switch; (3) Error Amplifier - compares the feedback voltage (FB pin) with the 0.6V internal reference; the output drives the PWM comparator through internal Type-II compensation; (4) Mode Selection - PFM version enters discontinuous conduction at light loads by skipping pulses, reducing switching losses and maintaining high efficiency; FPWM version maintains continuous conduction across all loads, ensuring constant switching frequency and lower output ripple; (5) Protection - cycle-by-cycle current limit caps peak switch current per cycle; if an overcurrent condition persists (output shorted), hiccup mode disables switching for a recovery period before retrying, preventing excessive thermal stress; thermal shutdown disables switching when junction temperature exceeds approximately 160C.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>BOOT<\/td><td>Bootstrap capacitor connection for high-side gate drive<\/td><\/tr><tr><td>2<\/td><td>VIN<\/td><td>Input voltage supply (4V to 36V)<\/td><\/tr><tr><td>3<\/td><td>EN<\/td><td>Enable input (high=enabled, low=shutdown)<\/td><\/tr><tr><td>4<\/td><td>FB<\/td><td>Output voltage feedback (connect resistor divider)<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>6<\/td><td>SW<\/td><td>Switch node (connect to inductor)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Automotive camera: 12V battery to 3.3V\/1.8V for image sensor and processor<\/li><li>Industrial sensor: 24V field supply to 5V for sensor signal conditioning<\/li><li>USB charger: 12V adapter to 5V\/600mA for USB power port<\/li><li>Battery-powered IoT: 6-12V battery to 3.3V, PFM mode for long battery life<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>TPS560430YFDBVT<\/td><td>SOT-23-6<\/td><td>Cut tape version<\/td><\/tr><tr><td>TI<\/td><td>TPS562201DDCR<\/td><td>SOT-23-6<\/td><td>4.5-17V\/2A, wider input, higher current<\/td><\/tr><tr><td>Monolithic Power<\/td><td>MP8759GD-Z<\/td><td>TSOT-23-6<\/td><td>4.5-21V\/2A, similar pinout<\/td><\/tr><tr><td>TI<\/td><td>TPS563200DDCR<\/td><td>SOT-23-6<\/td><td>4.5-17V\/3A, higher current class<\/td><\/tr><tr><td>TI<\/td><td>LMR16006YDDCR<\/td><td>SOT-23-6<\/td><td>4-60V\/600mA, wider input range<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/3745","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=3745"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/3745\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=3745"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=3745"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=3745"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=3745"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
