MT5033 - 800kHz Synchronous Step-up Converter

General Description

The MT5033 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.

M3TEK Preliminary Datasheet MT5033 800kHz Synchronous Step-up Converter with 6A Switches DESCRIPTION The MT5033 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 2.5A at 5V with a supply voltage down to 3V. The maximum peak current in the step-up switch is limited to a value of 6A. The MT5033 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.
