HA16138PS Datasheet

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

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 standb.

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 noisecancellation-filter-less impleme.
