Programmable Maximum Duty Cycle PWM Controller

FEATURES

DESCRIPTION

User Programmable Maximum PWM

Duty Cycle

The UCC3807 family of high speed, low power integrated circuits contains

all of the control and drive circuitry required for off-line and DC-to-DC fixed

frequency current mode switching power supplies with minimal external

parts count.

100mA Startup Current

Operation to 1MHz

These devices are similar to the UCC3800 family, but with the added fea-

ture of a user programmable maximum duty cycle. Oscillator frequency and

maximum duty cycle are programmed with two resistors and a capacitor.

The UCC3807 family also features internal full cycle soft start and internal

leading edge blanking of the current sense input.

Internal Leading Edge Blanking of

Current Sense Signal

1A Totem Pole Output

The UCC3807 family offers a variety of package options, temperature

range options, and choice of critical voltage levels. The family has UVLO

thresholds and hysteresis levels for off-line and battery powered systems.

Thresholds are shown in the table below.
