IRIS-X6757中文资料

Features

?7-pin SIP type full molded package, optimum IC for low-height SMPS.?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

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage

all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
