GENERAL DESCRIPTION
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.
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.
Consuming only 0.15W in standby, the IC features
over-current, hiccup mode short circuit, and under-
voltage protection mechanisms.
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.
