With many years of experience in the design of power management devices, Holtek has announced its entry into the ac-dc converter arena, with the release of two new ac to dc converter power management devices, the HT7A3942 and HT7A6003.
According to the company, the HT7A3942 and HT7A6003 are presently the only devices in the world which are fully pin compatible with the UC3842, which meet Energy Star 2.0 standby specifications and which have fully integrated ac-dc converter functions. The UC3842 device is unable to provide exceptionally low operating and standby current specifications, operate with a Green Mode nor operate at very low temperatures. Additionally the present ac-dc converter devices on the market are not fully pin compatible with the UC3842 device.
