HA16138PS
AC/DC Switching Converter Controller IC With High-Voltage Power MOS FET
ADE-204-032 (Z) Preliminary 1st Edition MAY 2000 Description
The HA16138PS is an IC with a high-voltage power MOS FET and current-mode type PWM controller mounted in a DILP-8 (DP-8) standard package, suitable for low-power power supplies in the 10 W class and below. The HA16138PS includes an energy-saving mode for holding down power consumption when on standby (no load). When the energy-saving mode is entered, the operating frequency is reduced to 1/4 the normal frequency, reducing power consumption. A starter circuit is also provided on-chip, eliminating the need for the external start-up resistance needed with previous controller ICs.
