Features

・For wide input voltage range, LLC current resonant power supply system

can be configured without PFC.

・Integrated high-side and low-side drive circuits, which can be directly

connected to the power MOSFET and operates with 50% duty cycle.

・The integrated startup circuit achieves downsized power supply and lower

power consumption.

・Operating mode can be selected from normal operation mode, low standby

mode, and ultralow standby mode (STB pin)

・During the low standby mode, standby power is lowered by the burst mode

operation.

・Integrated input filter X-capacitor discharge function decreases loss due to

discharge resistance.

・Low consumption current, 0.65mA (Vcc quiescent current).

・Since the dead time is set automatically within the IC, switch-through and

hard switching are prevented.

・Various protection functions: overcurrent (IS pin), overload (VW,FB pin),

overvoltage (VH,VCC pin) and overheat.

・Integrated level-fixed brown-in/out function (VH pin)

・Level-adjustable brown-in/out function (BO pin)

・Various condition settings, including external latch-off function, overcurrent

protection (detection by IS pin) delay time setting, operation setting in

standby mode, and PFC with/without setting, can be made (MODE pin).

・Built-in circuit for prevention of low-voltage malfunction (VCC,VB pin)

・Package: SOP-16 (compliant with JEDEC)
