DESCRIPTION
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.
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.
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.
