TPS63060 Datasheet PDF – Buck-Boost Converter

Part Number : TPS63060, TPS6306x

Function : High Input Voltage, Buck-Boost Converter With 2-A Switch Current

Package : 3 mm × 3 mm, 10-pin, WSON (DSC), PowerPAD package

Manufacturers : Texas Instruments

Pinouts :
TPS63060 datasheet

Description :

The TPS6306x devices provide a power supply solution for products powered by either three-cell up to six-cell alkaline, NiCd or NiMH battery, or a one-cell or dual-cell Li-Ion or Li-polymer battery. Output currents can go as high as 2-A while using a dual-cell Li-Ion or Li-polymer battery, and discharge it down to 5 V or lower. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency.


1. Input Voltage Range: 2.5 V to 12 V
2. Efficiency: Up to 93%
3. Power-Save Mode for Improved Efficiency at Low Output Power
4. Buck-Boost Overlap Control
5. Load Disconnect During Shutdown
