Inrush Current Control
! Separated PFC OVP pin
! Separated Power Ground and Analog Ground
! PWMSDB to turn off PWMCLK without disturbing PFC
section
! 23V Bi-CMOS process
! VIN OK guaranteed turn on PWM Clock at 2.5V instead of
1.5V
! Internally synchronized leading edge PFC and trailing edge
PWM Clock in one IC
! Slew rate enhanced transconductance error amplifier for
ultra-fast PFC response
! Low start-up current (100μA typ.)
! Low operating current (3.0mA type.)
! Low total harmonic distortion, high PF
! Reduces ripple current in the storage capacitor between the
PFC and PWM sections
! Average current, continuous or discontinuous boost leading
edge PFC
! VCC OVP Comparator
! Low Power Detect Comparator
! PWM configurable for current mode or voltage mode
operation
! Current fed gain modulator for improved noise immunity
! Brown-out control, over-voltage protection, UVLO, and soft
start, and Reference OK
