TPS5110 Datasheet Synchronous Buck PWM Controller

Manufacturer: Texas Instruments

General Description

The TPS5110 provides one PWM-mode synchronous buck regulator controller (SBRC) and one low drop-out (LDO) regulator controller.

The TPS5110 supports a low-voltage/high-current power supply for I/O and other peripherals in modern digital systems.

The SBRC of the TPS5110 automatically adjusts from PWM mode to SKIP mode to maintain high efficiency under all load conditions.
