Overview
M3TEK Preliminary Datasheet MT5032 800kHz Synchronous Step-up Converter with 5.
5A Switches DESCRIPTION The MT5032 devices provide a power supply solution for products powered by either a one-cell Li-Ion or Li-polymer battery.
The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip.
It provides high efficient power conversion and is capable of delivering output currents up to 2.
1A at 5.
3V at a supply voltage down to 2.
9V.
The maximum peak current in the step-up switch is limited to a value of 5.
5A.
The MT5032 operates at 800kHz switching frequency and enters pulse-skip-mode (PSM) operation at light load currents to maintain high efficiency over the entire load current range.
During shutdown, the load is completely disconnected from the battery.
