Peak current-mode control is employed to achieve simple control-loop compensation and cycle-by-cycle current limiting. A quiescent current of 75\u00b5A makes the device suitable for battery-powered systems. An ultra-low 2\u00b5A shutdown current can further prolong battery life. Internal loop compensation eliminates the tedious task of loop compensation design and minimizes external components. The device has an option for constant frequency FPWM mode to achieve small output-voltage ripple at light load.","working_principle":"The LMR23630 employs peak current-mode control architecture. The error amplifier compares the feedback voltage (FB pin) with an internal reference and drives the COMP node. The COMP voltage sets the peak current threshold for the high-side MOSFET. When the high-side switch current reaches the threshold, it turns off and the low-side synchronous MOSFET turns on. In PFM mode, the device reduces switching frequency at light loads to maintain efficiency. The internal oscillator generates the switching clock at 400kHz or 2.1MHz based on the RT pin configuration. Protection circuits include cycle-by-cycle current limit, hiccup-mode output short protection, and thermal shutdown.","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 driver<\/td><\/tr><tr><td>2<\/td><td>VIN<\/td><td>Input supply voltage (4V-36V)<\/td><\/tr><tr><td>3<\/td><td>EN\/SYNC<\/td><td>Enable and frequency synchronization input<\/td><\/tr><tr><td>4<\/td><td>RT<\/td><td>Switching frequency selection pin<\/td><\/tr><tr><td>5<\/td><td>FB<\/td><td>Feedback input from output voltage divider<\/td><\/tr><tr><td>6<\/td><td>AGND<\/td><td>Analog ground<\/td><\/tr><tr><td>7<\/td><td>PGOOD<\/td><td>Power-good open-drain output<\/td><\/tr><tr><td>8-9<\/td><td>PGND<\/td><td>Power ground<\/td><\/tr><tr><td>10-11<\/td><td>SW<\/td><td>Switch node connection to output inductor<\/td><\/tr><tr><td>12<\/td><td>VCC<\/td><td>Internal LDO output, bypass with capacitor<\/td><\/tr><\/table>","application_scenarios":"<ul><li><b>Industrial PLC Power Supply<\/b>: Provides 5V\/3.3V rail from 24V industrial bus with >92% efficiency and hiccup short-circuit protection<\/li><li><b>Battery-Powered Asset Tracker<\/b>: 75\u00b5A no-load quiescent current extends battery life in always-on tracking devices<\/li><li><b>Building Automation HVAC<\/b>: Wide 4V-36V input accommodates battery backup and unregulated adapter supplies<\/li><li><b>Elevator Control System<\/b>: Robust 36V input rating with integrated protection for harsh electrical environments<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>LMR23625FDRRR<\/td><td>TI<\/td><td>2.5A version, pin-to-pin compatible<\/td><\/tr><tr><td>LMR23610FDRRR<\/td><td>TI<\/td><td>1A version, pin-to-pin compatible<\/td><\/tr><tr><td>LMR16030PDDAR<\/td><td>TI<\/td><td>60V input, 3A, HSOIC-8 package<\/td><\/tr><tr><td>TPS54331DDAR<\/td><td>TI<\/td><td>3.5V-28V input, 3A, HSOIC-8<\/td><\/tr><tr><td>MP8759GD-Z<\/td><td>MPS<\/td><td>18V, 5A, QFN-12 (3x3mm)<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6997","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=6997"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6997\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6997"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6997"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6997"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6997"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
