High Performance Off-Line Controller

ActiveSwitcher^TMIC Family

FEATURES

GENERAL DESCRIPTION

• Lowest Total Cost Solution

The ACT30 is a high performance green-energy off-

line 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-B), resulting in lowest total cost

solution.

• 0.15W Standby Power

• Emitter Drive Allows Safe NPN Transistor

Flyback Use

• Hiccup Mode Short Circuit

• Current Mode Operation

The ACT30 design has six 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 versions) for 65kHz or

100kHz switching frequency and with 400mA or

800mA current limit.

• 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

Consuming only 0.15W in standby, the IC features

over-current, hiccup mode short circuit, and under-

voltage protection mechanisms.

APPLICATIONS

• Battery Chargers

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.

• Power Adaptors

• Standby Power Supplies

• Appliances

• Universal Off-Line Power Supplies
