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.

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 implementation

• Built-in over voltage protection circuit

• Built-in over temperature protection circuit
