TPS63061DSCR

Понижающий-повышающий импульсный стабилизатор, фиксированный, 2.5В-12В (Vin), 5В и 2A, SON-10.

The TPS63061DSCR is a 93% Efficient 2.25A Switch Current Limit Buck-boost Converter with 1A switches that provide a power supply solution for products powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery or a one-cell Li-ion or Li-polymer battery. 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 2.25A. The output voltage is programmable using an external resistor divider or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery.
