Product Overview
The TPS63070 is a Texas Instruments buck-boost converter for Power_Management designs requiring regulated conversion across overlapping input and output ranges. It accepts 2.0 to 16 V at VIN during operation and supports an adjustable 2.5 to 9 V output range for the TPS63070 version. The device title rating lists a 3.6 A switch current, with up to 95% efficiency and 2 A output current capability in buck mode or in boost mode at VIN=4 V and VOUT=5 V.
The device is supplied in a VQFN package with a 2.5 mm x 3 mm nominal body. Recommended external operating components include 0.7 to 2.8 uH effective inductance, 4.7 uF minimum input capacitance at VIN, 100 nF VAUX capacitance, and 15 to 470 uF total output capacitance at VOUT.
Control and monitoring functions include EN, PS/SYNC, VSEL, and PG pins. The converter supports 2.4 MHz fixed-frequency operation and synchronization, power-good thresholds referenced to VOUT, undervoltage lockout, and thermal shutdown.
