LM5027A Datasheet (Texas Instruments) - Voltage Mode Active Clamp Controller

LM5027A, Voltage Mode Active Clamp Controller

The LM5027A is a functional variant of the LM5027 active clamp PWM controller.

The functional difference of the LM5027A is that the maximum duty cycle of the LM5027A is decreased from 91% to 71%.

In addition, the oscillator timing equation has been modified.
