FEATURES
GENERAL DESCRIPTION
* High Efficiency: Up to 96%
The MT3428 is a constant frequency, dual
* 1.5MHz Constant Frequency Operation
high-efficiency PWM step-down converter. The
* Dual 800mA Output Current
device integrates a main switch and a synchronous
* No Schottky Diode Required
rectifier for high efficiency without an external
* 2V to 6V Input Voltage Range
Schottky diode. It is ideal for powering portable
* PFM Mode for High Efficiency in Light Load
equipment that runs from a single cell Lithium-Ion
* Output Voltage as Low as 0.6V
(Li+) battery. The output voltage can be regulated as
* 100% Duty Cycle in Dropout
low as 0.6V. The MT3428 can also run at 100% duty
* Low Quiescent Current: 20μA
cycle for low dropout operation, extending battery life
* Short Circuit Protection
in portable system. This device offers two operation
* Thermal Fault Protection
modes, PWM control and PFM Mode switching
* Inrush Current Limit and Soft Start
control, which allows a high efficiency over the wider
* <1μA Shutdown Current
range of the load.
