VoltageDescription
HL9701 is a secondary-side synchronous rectifier (SR)
controller for isolated flyback converters. By Implementing
proprietary turn-off control algorithm, HL9701 can reliably
support discontinuous conduction mode (DCM), Quasi-
Resonant (QR) and continuous conduction mode (CCM)
operation, which will help to design robust flyback
converters. The SR turn-off threshold control optimizes
the body diode conduction of SR MOSFET while
guaranteeing stable and robust SR operation against
noise and disturbance caused by the circuit parasitic.
HL9701 integrates a 30V rated input voltage LDO along
with Low Vin under-voltage lockout (UVLO) voltage, which
allows wide power supply output voltage range.
HL9701 supports high side or low side SR MOSFET
placement which allows customer to design the power
supply system with flexibility. HL9701 is available in a
space-saving SOT23-6 package.
