TPS63036 (ACTIVE) High Efficient Single Inductor Buck-Boost Converter with 1-A Switches

 

Description

The TPS63036 is a non-inverting buck-boost converter able to provide a regulated output voltage from an input supply that can be higher or lower than the output voltage. The buck-boost converter is based on a fixed frequency, pulse width modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters power save mode to maintain high efficiency over a wide load current range. The power save mode can be disabled, forcing the converter to operate at a fixed switching frequency.

The maximum average current in the switches is limited to a typical value of 1000 mA. The output voltage is programmable using an external resistor divider.

The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the supply.
