Product Overview
The TPS63050 is a Texas Instruments Power_Management Power_IC implemented as a single-inductor buck-boost converter. It is specified for a recommended 2.5 to 5.5 V input range and a 2.5 to 5.5 V output voltage range, with 0.5 A recommended output current. In operating descriptions, it supports 500 mA continuous output current in boost mode when VIN >= 2.5 V and VOUT = 3.3 V, and 1 A continuous output current in buck mode.
The device uses fixed-frequency PWM operation at 2.5 MHz typical switching frequency and has a 1 A typical maximum average switch current limit. Operating mode selection supports automatic Power Save Mode or forced PWM mode through the PFM/PWM pin. The TPS63050 version provides an adjustable output using a 0.8 V typical feedback regulation voltage, while TPS63051 is listed with a 3.3 V fixed output option.
Package options include 12-pin DSBGA/WCSP at 1.56 mm x 1.16 mm and 12-pin HotRod VQFN/RMW at 2.50 mm x 2.50 mm. The recommended external power stage values include 1 uH to 2.2 uH effective inductance with 1.5 uH nominal and 10 uF nominal effective output capacitance. The device is specified for -40°C to 85°C ambient operation and -40°C to 125°C virtual junction operation.
