pin assignments
COMP:
This pin provides the output of the error amplifier for compensation. In addition, the COMP pin is
frequently used as a control port by utilizing a secondary-side error amplifier to send an error signal across the
secondary-primary isolation boundary through an opto-isolator.
CS:
The current sense pin is the non-inverting input to the PWM comparator. This is compared to a signal
proportional to the error amplifier output voltage. A voltage ramp can be applied to this pin to run the device with
a voltage mode control configuration.
FB:
This pin is the inverting input to the error amplifier. The non-inverting input to the error amplifier is internally
trimmed to 2.5 V
±
1%.
GND:
Ground return pin for the output driver stage and the logic level controller section.
OUT:
The output of the on-chip drive stage. OUT is intended to directly drive a MOSFET. The OUT pin in the
UCC38C40, UCC38C42 and UCC38C43 is the same frequency as the oscillator, and can operate near 100%
duty cycle. In the UCC38C41, UCC38C44 and the UCC38C45, the frequency of OUT is one-half that of the
oscillator due to an internal T flipflop. This limits the maximum duty cycle to < 50%.
RT/CT:
Timing resistor and timing capacitor. The timing capacitor should be connected to the device ground
using minimal trace length.
VDD:
Power supply pin for the device. This pin should be bypassed with a 0.1-
μ
F capacitor with minimal trace
lengths. Additional capacitance may be needed to provide hold up power to the device during startup.
VREF:
5-V reference. For stability, the reference should be bypassed with a 0.1-
μ
F capacitor to ground using
the minimal trace length possible.
