IRIS-W6753
Features
• 6-pin SIP type full molded package, optimum IC for low-height SMPS, with
distance between high and low voltage pin 1.8 mm with pin elimination.
• Oscillator is provided on the monolithic control with adopting On-Chip
Trimming Technology
• Small temperature characteristics variation by adopting a comparator to
compensate for temperature on the control part.
• Low start-up circuit current (100uA max)
•Avalanche energy guaranteed MOSFET with high VDSS

The built-in power MOSFET simplifies the surge absorption
circuit since the MOSFET guarantees the avalanche energy.

No VDSS de-rating is required.
• Built-in constant voltage drive circuit
• Built-in step drive circuit
• Built-in low frequency PWM mode (22 kHz)
• UVLO Burst Standby
• Two operational modes by auto switching functions according to load

For middle~heavy load operation : QR mode

For light~middle load operation : 1 Bottom Skip mode
• Various kinds of protection functions

Pulse-by-Pulse OvercurrentProtection (OCP)

OvervoltageProtection with Latch mode (OVP)

Overload Protection with Latch mode (OLP)

The maximum limit of on-time
