DESCRIPTION

FEATURES

The A7220A is a high efficiency current-mode

synchronous, 20V/2A buck converter. Its input

voltage ranges from 4.5V to 20V and it provides an

adjustable regulated output voltage from 0.923V to

17V while delivering up to 2A of output current.



Adjustable Output Voltage, V_FB=0.923V

Maximum output current is 2A

Range of operation input voltage: Max 20V

Standby current: 60uA (typ.)

Operating current at zero load: 0.1mA (typ.)

Line regulation: 0.1%/V (typ.)

The internal synchronous switches increase

efficiency and eliminate the need for an external

Schottky diode. The switching frequency is set to

350KHz.

Load regulation: 10mV (typ.)

High efficiency, up to 94%

Environment Temperature: -20°C~85°C

Available in SOP8 Package

A7220A consists of many protection block such as

UVLO, thermal protection and output short circuit

protection.
