ACT30

HIGH PERFORMANCE OFF-LINE CONTROLLER

ActiveSwitcher^TMIC Family

FEATURES

GENERAL DESCRIPTION

ꢀ

Lowest Total Cost Solution

The ACT30 is

high performance

green-energy offline power supply controller. It

features a scalable driver for driving external

NPN or MOSFET transistors for line voltage

switching. This proprietary architecture enables

many advanced features to be integrated into a

small package (TO-92 or SOT23-5), resulting in

lowest total cost solution.

0.15W Standby Power

Emitter Drive Allows Safe NPN Flyback Use

Hiccup Mode Short Circuit

Current Mode Operation

Over-Current Protection

Under-voltage Protection with Auto-restart

Proprietary Scalable Output Driver

Flexible Packaging Options (including TO-92)

65kHz or 100kHz Switching Frequency

Selectable 0.4A to 1.2A Current Limit

The ACT30 design has 6 internal terminals

and is a pulse frequency and width modulation IC

with many flexible packaging options. One

combination of internal terminals is packaged in

the space-saving TO-92 package (A/B/C/D

versions) for 65kHz or 100kHz switching

frequency and with 400mA or 800mA current limit.

The E version (SOT23-5) can be configured for

higher current limit.

APPLICATIONS

ꢀ

Battery Chargers

Power Adaptors

Consuming only 0.15W in standby, the IC

features over-current, hiccup mode short circuit,

and under-voltage protection mechanisms.

Standby Power Supplies

Appliances

Universal Off-line Power Supplies

The ACT30 is ideal for use in high

performance universal adaptors and chargers.

For highest performance versus cost and

smallest PCB area, use the ACT30 in

combination with the ACT32 CV/CC Controller.
