TPS61010DGS

Импульсный повышающий DC-DC стабилизатор, регулируемый, 800мВ-3.3В (Vin), 1.5В-3.3В, 250мА, VSSOP-10.

The TPS61010DGS is a low input voltage synchronous Boost Converter with adjustable output. The boost converter intended for systems that are typically operated from a single- or dual-cell nickel-cadmium (NiCd), nickel-metal hydride (NiMH) or alkaline battery. The converter output voltage can be adjusted from 1.5V to a maximum of 3.3V, by an external resistor divider or, is fixed internally on the chip. The device provides an output current of 200mA with a supply voltage of only 0.9V. The converter starts up into a full load with a supply voltage of only 0.9V and stays in operation with supply voltages down to 0.8V. The converter is based on a fixed frequency, current mode, pulse-width-modulation (PWM) controller that goes automatically into power save mode at light load. It uses a built-in synchronous rectifier, so, no external Schottky diode is required and the system efficiency is improved. The current through the switch is limited to a maximum value of 1300mA.
