FEATURES

Both PFC and PWM have the Green Mode to meet blue
angel and energy star spec.
􀂋 10-Pin SOIC package
􀂋 PWM pulse skipping for the green mode
􀂋 Use RAC as the Startup resistor around 5 Mega Ohm at
IAC pin
􀂋 It can use the HV bipolar to start up the chip and it helps
green mode.
􀂋 Easy to configure into Boost Follower
􀂋 Enable lowest BOM for power supply with PFC
􀂋 Internally synchronized PFC and PWM in one IC
􀂋 Patented slew rate enhanced voltage error amplifier with
advanced input current shaping technique
􀂋 Universal Line Input Voltage
􀂋 CCM boost or DCM boost with leading edge modulation
PFC using Input Current Shaping Technique
􀂋 Feedforward IAC pin to do the automatic slope
compensation
􀂋 PFCOVP, VCCOVP, Precision -1V PFC ILIMIT, PFC
Tri-Fault Detect comparator to meet UL1950
􀂋 Low supply currents; start-up: 100uA typical, operating
current: 2mA typical.
􀂋 Synchronized leading PFC and trailing edge modulation
PWM to reduce ripple current in the storage capacitor
between the PFC and PWM sections and to reduce
switching noise in the system
􀂋 VINOK Comparator to guarantee to enable PWM when
PFC reach steady state
􀂋 High efficiency trailing-edge current mode PWM
􀂋 Exact 50% PWM maximum duty cycle
􀂋 UVLO, REFOK, and brownout protection
􀂋 Digital PFC and PWM soft start, ~10mS
􀂋 Precision PWM 1.5V current limit for current mode
operation
􀂋 PWMtrifault to sense DC to DC short and Turn off PFC at
GMth
􀂋 PWMtrifault also can be programmed to do the Thermal
Protection
