High Performance
ActivePSR
TM
Primary Switching Regulator
FEATURES
Patented Primary Side Regulation
Technology
few external components.
The ACT364 ensures safe operation with complete
protection against all fault conditions. Built-in
protection circuitry is provided for output short-
circuit, output over-voltage, line under-voltage, and
over temperature conditions.
The ACT364
ActivePSR
TM
is optimized for high
performance, cost-sensitive applications, and
utilizes Active-Semi’s proprietary primary-side
feedback architecture to provide accurate constant
voltage, constant current (CV/CC) regulation
without the need of an opto-coupler or reference
device. Integrated line and primary inductance
compensation circuitry provides accurate constant
current operation despite wide variations in line
voltage and primary inductance. Integrated output
cord resistance compensation further enhances
output accuracy. The ACT364 achieves excellent
regulation and transient response, yet requires less
than 150mW of standby power.
The ACT364 is optimized for compact size 2W to
6.3W charger applications. It is available in space-
saving 6 pin SOT23-6 package.

GENERAL DESCRIPTION
The ACT364 belongs to the high performance
patented
ActivePSR
TM
Family of Universal-input
AC/DC off-line controllers for battery charger and
adapter applications. It is designed for flyback
topology working in discontinuous conduction mode
(DCM). The ACT364 meets all of the global energy
efficiency regulations (CEC, European Blue Angel,
and US Energy Star standards) while using very
Innovative Power
