MT5030

M3TEK Preliminary Datasheet MT5030 95% Efficient 1.2MHz Synchronous Step-up Converter With 6A Switches DESCRIPTION The MT5030 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 6A. The MT5030 operates at 1.2MHz switching frequency and enters pulse-skip-mode (PSM) operation at light load currents to maintain high efficiency over the entire load current range. The PSM mode extends the battery life by reducing the quiescent current to 50µA (typ) during light load operation. A low-EMI mode is implemented to reduce ringing and, in effect, lower radiated electromagnetic energy when ...
