HA16138PS - AC/DC Switching Converter Controller IC With High-Voltage Power MOS FET

General 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.

Key Features

  • Built-in high-voltage power MOS FET.
  • Energy-saving mode (power saving through reduction of operating frequency to 1/4 normal frequency when on standby).
  • Built-in starter circuit, reducing power loss of start-up resistance when on standby (external start-up resistance not necessary).
  • Built-in soft start circuit, eliminating need for external connection.
  • Remote on/off function, enabling power saving by halting PWM output without turning off power suppl.

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.
