5MHz, 1A Synchronous Step-Down Converter
Product Description
The GS5581/A are high-efficiency, high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1A output currents.
The GS5581/A can operate over a wide input
voltage range from 2.
3V to 6V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery.
The output
voltage can be regulated as low as 0.
6V.
The GS5581/A can also run at 100% duty cycle for low dropout operation, extending battery life in portable system.
This device offers two operation modes, PWM mode and...
