EUP3010/A

1.5MHz,1A Synchronous

Step-Down Converter with Soft Start

DESCRIPTION

FEATURES

The EUP3010/A is a constant frequency, current mode,

PWM step-down converter. The device integrates a

main switch and a synchronous rectifier for high

efficiency. The 2.5V to 5.5V input voltage range makes

the EUP3010/A ideal for powering portable equipment

that runs from a single cell Lithium-Ion (Li+) battery or

3-cell NiMH/ NiCd batteries. The output voltage can be

regulated as low as 0.6V. The EUP3010/A supports up

to 1A load current and can also run at 100% duty cycle

for low dropout applications, extending battery life in

portable systems.

Switching frequency is internally set at 1.5MHz,

allowing the use of small surface mount inductors and

capacitors. The internal synchronous switch increases

efficiency while eliminates the need for an external

Schottky diode. The EUP3010/A is available in an

adjustable output or fixed output 1.2V ,1.8V and 3.3V.
