act30 pdf

The ACT30 is a 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.
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.
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.
