Description



Features:

•6-pin SIP type full molded package, optimum IC for low-height SMPS,
  distance between high and low voltage pins is 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 Overcurrent Protection (OCP)
- Overvoltage Protection with Latch mode (OVP)
- Overload Protection with Latch mode (OLP)
- The maximum limit of on-time

Description

IRIS-W6754 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for Quasi-Resonant (including low frequency PWM) fly-back converter type SMPS (Switching Mode Power Supply) applications. This IRIS-W6754 realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external component count and simplifying the circuit design.
