A7542

DC-DC CONVERTER(BOOST)

1MHz, 3A STEP UP REGULATOR

AiT Semiconductor Inc.

DESCRIPTION

FEATURES

A7542 is an asynchronous PWM boost converter

using a constant frequency peak current mode. An

external Schottky diode is needed. At light load,

A7542 works in the light load mode. The supply

current during the light mode is 100uA and less than

1uA in shutdown mode, together with the 130mΩ

internal NMOS power transistor guarantees high

efficiency in the whole output load current range. Up

to 3A peak current, Let A7542 can provide 1.5A

output load current, which is suitable to use as MID

and mobile power supply. The input voltage

2.5~5.5V.The operating frequency is internally set at

1MHz.



High Efficiency: Up to 92%

1.0MHz Constant Switching Frequency

Switch current up to 3A

Low R _DS(ON): 0.13Ω

Accurate Reference:0.6V

Tiny External Components
