Advanced Voltage Mode Pulse Width Modulator

FEATURES

DESCRIPTION

700kHz Operation

The UCC35701/UCC35702 family of pulse width modulators is intended for

isolated switching power supplies using primary side control. They can be

used for both off-line applications and DC/DC converter designs such as in

a distributed power system architecture or as a telecom power source.

Integrated Oscillator/ Voltage Feed

Forward Compensation

Accurate Duty Cycle Limit

Accurate Volt-second Clamp

Optocoupler Interface

The devices feature low startup current, allowing for efficient off-line start-

ing, yet have sufficient output drive to switch power MOSFETs in excess of

500kHz.

Voltage feed forward compensation is operational over a 5:1 input range

and provides fast and accurate response to input voltage changes over a

4:1 range. An accurate volt-second clamp and maximum duty cycle limit

are also featured.

Fault Counting Shutdown

Fault Latch off or Automatic Shutdown

Soft Stop Optimized for Synchronous

Rectification

Fault protection is provided by pulse by pulse current limiting as well as the

ability to latch off after a programmable number of repetitive faults has oc-

curred.

1A Peak Gate Drive Output

130mA Start-up Current

750mA Operating Current

Two UVLO options are offered. UCC35701 family has turn-on and turn-off

thresholds of 13V/9V and UCC35702 family has thresholds of 9.6V/8.8V.

The UCC35701/2 and the UCC25701/2 are offered in the 14 pin SOIC (D),

14 pin PDIP (N) or in 14 pin TSSOP (PW) packages. The UCC15701/2 is

offered in the 14 pin CDIP (J) package.
