Product Description

Description
The IC products in this series are primary control switching regulator control IC’s appropriate for obtaining
stabilized DC voltages from commercial AC power.
Features
• Operating frequencies up to a high 600 kHz
• Built-in pre-driver circuit for driving power MOS FET
• Built-in timer latch over-current protection function (HA16107)
• The OCL enables intermittent operation by an ON/OFF timer for prevention of secondary overcurrent.
(HA16108)
• The UVL function (under voltage lockout) is applied to both Vin and Vref.
• ON/OFF reset: an auto-reset function which is based on the time constant of an external capacitor and
observation of drops in Vin.
• Since the over-voltage protection function OVP (the TL pin) only observes voltage drops in Vin, it is
possible to use the OVP and ON/OFF pin for independent purposes.
• Built-in 34 V Zener diode between Vin and ground.
Functions
• 6.45 V reference voltage
• Triangle wave generator
• Error amplifier
• Under voltage lockout protector
• PWM comparator
• Pulse-by-pulse current limitting
• Timer-latch current limitting (HA16107)
• ON/OFF timer function (HA16108)
• Soft start and quick shutdown
• Output circuit for power MOS FET driving
