TPS65051RSMR Description

Short technical summary and product information.

The TPS65051RSMR from Texas Instruments is a versatile 6-channel power management integrated circuit (PMIC) suitable for battery-powered devices. It features two highly efficient step-down converters capable of delivering up to 1A (DCDC1) and 0.6A (DCDC2), with an input voltage range of 2.5V to 6V. The device also includes two 400mA and two 200mA general-purpose LDOs, operating from an input voltage range of 1.5V to 6.5V.

 

With up to 95% efficiency and a low quiescent current of 32μA for both DC-DC converters, the TPS65051RSMR is optimized for power conservation. It operates at a fixed frequency of 2.25MHz and offers digital voltage selection for both DC-DC converters and LDOs. The output voltage accuracy in PWM mode is ±1%.

 

Packaged in a 32-VQFN (4x4) with an exposed pad, this surface-mount device is designed for applications such as cell phones, smartphones, WLAN devices, and PDAs. Its integrated power solutions make it ideal for powering OMAP™ and low-power TMS320™ DSPs, as well as application processors like the Samsung S3C24xx.
