•Small sized 8-pin DIP type full molded package, optimum IC for low-

height SMPS

•Off-timer circuit is provided on the monolithic control IC

• Low start-up circuit current (10uA typ)

•Low circuit current at operation (1.5mA typ)

• Avalanche energy guaranteed MOSFET with high VDSS

•Built-in Start-up circuit (the power loss in the start-up circuit is

reduced by cutting off the start-up circuit after the IC starts its

operation.)

•Auto Burst Stand-by (realizing input power<0.1W at no load)

•Auto Bias Function (stable burst operation without the interference on

transformer)

•Two operational modes by auto switching functions

•Built-in Leading Edge Blanking Function

•Built-in constant voltage drive circuit

•Various kinds of protection functions

Descriptions

IRIS-A6151 is a hybrid IC consisting of a power MOSFET and a controller IC, designed for PRC

fly-back converter type SMPS (Switching Mode Power Supply) applications, applicable for PRC

operation for small power SMPS. This IC realizes downsizing and standardizing of a power supply

system reducing external component count and simplifying the circuit design.

Note: PRC is abbreviation for “Pulse Ratio Control” (On-width control with fixed OFF-time).

Features

Typical Connection Diagram

Note 1: The pout (W) represents the thermal rating at PRC Operation. The peak power output is obtained by

approximating 120 to 140% of the above listed value. When the output voltage is low and ON-duty is narrow, the

Pout (W) shall become lower than that of above value.

For normal operation: PRC mode

For stand-by operation (at light load): Burst mode

The built-in power MOSFET simplifies the surge absorption

circuit since the MOSFET guarantees the avalanche energy.

No VDSS de-rating is required.
