Introduction

AI Translation

TPS65262-1 is a monolithic triple synchronous step-down (buck) converter with 3A/1A/1A output current. The wide input supply voltage range of 4.5V to 18V covers most intermediate bus voltages operating from 5V, 9V, 12V, or 15V power buses. This converter with constant-frequency peak current mode control is designed to simplify its application while enabling designers to optimize the system for the target application. The device operates at a fixed switching frequency of 600kHz. To reduce external component count, loop compensation for buck2 and buck3 has been integrated. The 180° out-of-phase operation between buck1 and buck2/buck3 (buck2 and buck3 operate in phase) minimizes input filter requirements. Under light-load conditions, the device automatically operates in pulse skipping mode (PSM) to deliver high efficiency by reducing switching losses.

The TPS65262-1 integrates two LDOs with an input voltage range of 1.3V to 5.5V, continuous output current of 350/150mA, and independent enable and adjustable output voltage features.

The TPS65262-1 features automatic power sequencing by driving the MODE pin high and configuring the EN1, EN2, and EN3 pins.

The device provides overvoltage protection, overcurrent protection, short-circuit protection, and overtemperature protection. The power-good pin asserts when any buck output voltage falls outside the regulation range.
