It integrates: two step-down DC-DC converters (1.6A each, 2.25MHz), eight LDO regulators (10-300mA each), a 32kHz RTC oscillator, and I2C control interface. The two DC-DC converters power the processor core (VDD1) and memory\/IO (VDD2) with 95% efficiency. Each converter uses DCS-Control for fast transient response. The eight LDOs provide low-noise power for analog peripherals (PLL, ADC, USB PHY, audio codec). The A3A1 configuration defines the default voltage settings and power-up sequence stored in OTP (One-Time Programmable) memory: VDD1 ramps to 1.2V first, then VDD2 to 1.8V, then LDOs in sequence. The I2C interface allows runtime voltage adjustment for DVFS (Dynamic Voltage and Frequency Scaling). The PWRON pin triggers power-up with configurable debounce. The NRESW pin provides a system reset output. The GPIO pins are individually configurable as: voltage rail enable, interrupt output, or general-purpose I\/O. The device supports multiple sleep states: ACTIVE (all rails on), SLEEP (DC-DCs reduced, some LDOs off), and OFF (only RTC running). The -A3A1RSLR suffix specifies QFN-48, A3 configuration, tape-and-reel. Applications include: BeagleBone power management, tablet PMIC, and embedded Linux system power.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1-4<\/td><td>VCC1-4\/BBAT<\/td><td>Power<\/td><td>Step-down converter inputs \/ battery backup<\/td><\/tr><tr><td>5-12<\/td><td>LDO1-LDO8<\/td><td>Output<\/td><td>8 LDO regulators (1.0-3.3V, 10-300mA each)<\/td><\/tr><tr><td>13-16<\/td><td>VDD1-2\/SW1-2<\/td><td>Power\/I\/O<\/td><td>Step-down converter 1-2 outputs (up to 1.6A each)<\/td><\/tr><tr><td>17-24<\/td><td>I2C\/SCL\/SDA\/PWRON\/NRESW<\/td><td>I\/O\/Power<\/td><td>I2C control \/ power-on \/ reset<\/td><\/tr><tr><td>25-32<\/td><td>GPIO0-7\/CLK32K<\/td><td>I\/O<\/td><td>General-purpose I\/O \/ 32kHz clock output<\/td><\/tr><tr><td>33-48<\/td><td>GND\/VCC\/TS\/DIE_ID<\/td><td>Power\/Misc<\/td><td>Ground, supplies, temperature sensor, die ID<\/td><\/tr><\/table>","application_scenarios":"<li>Industrial control<\/li><li>Consumer electronics<\/li><li>Communication equipment<\/li><li>Automotive electronics<\/li>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Texas Instruments<\/td><td>TPS65910A3A1RSLR<\/td><td>QFN-48<\/td><td>Same device, TI brand<\/td><\/tr><tr><td>Texas Instruments<\/td><td>TPS65910A2A1RSLR<\/td><td>QFN-48<\/td><td>Different default configuration (A2 vs A3)<\/td><\/tr><tr><td>Texas Instruments<\/td><td>TPS65920A3A1RSLR<\/td><td>QFN-48<\/td><td>Similar PMIC for DaVinci processors<\/td><\/tr><tr><td>Richtek<\/td><td>RT5028AGQW<\/td><td>QFN-40<\/td><td>4 buck + 4 LDO PMIC, Richtek brand<\/td><\/tr><tr><td>NXP<\/td><td>PF0100F2AEP<\/td><td>BGA-56<\/td><td>Multi-rail PMIC for i.MX6, NXP brand<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5618","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=5618"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5618\/revisions"}],"predecessor-version":[{"id":6201,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/5618\/revisions\/6201"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=5618"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=5618"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=5618"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=5618"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
