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.
During shutdown, the load is completely
disconnected from the battery.
