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. The starter circuit in this IC is turned
off automatically after the IC starts up, enabling the start-up resistance power consumption to be decreased.
The HA16138PS includes a soft start circuit, OVP circuit, and remote on/off circuit, making it possible to
configure a simple protection circuit with fewer external parts than previously. Also provided are a current
sense resistance and a leading edge blanking circuit that masks spike noise on current sense input, making
noise reduction in a power supply set comparatively easy.
The HA16138PS is equipped with an error amp circuit inverting input (FB) pin and output (COMP) pin,
enabling special-purpose design for both flyback system secondary-side output voltage detection and
primary-side back-up transformer output voltage detection types.
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
supply
• Built-in current sense resistance and leading edge blanking circuit, for sense-resistance-less and noise-
cancellation-filter-less implementation
• Built-in over voltage protection circuit
• Built-in over temperature protection circuit
