BF1501 Series
Off Line AC/DC Switcher IC
General Description
The THC0X switcher ICs cost effectively replace all
power supplies up to 5W output power based on
unregulated isolated linear transformer (50/60HZ).
Unlike conventional PWM (pulse width modulation)
controllers, it regulates the output voltage in a new
method of off-time modulation control. The controller
consists of a VCO (voltage control oscillator), Sense
and logic circuit, VDD pin, under-voltage lockout
circuit, over-voltage protection, current limited circuit,
leading edge blanking, over load protection and fault
condition auto-restart. They are ideal low power
AC/DC adapter/charger for cell phones.
Applications
„ AC/DC adapter/charger for cell/cordless phones,
digital cameras, MP3/portable audio devices etc
„ LED Lighting
„ Replacements for linear transformers and RCC
