Primary side startup controller

Functional description

3.6

Auto-restart timer

A fixed timer of TAR sec is available for various fault conditions. The timer is operated from a free running oscil-

lator inside EZ-PD™ PAG1P. Free running oscillator will be running at FOSC.

3.7

Protection and fault condition

Primarily there are four types of protection actions used in various fault conditions.

1. Autorestart: In this mode, EZ-PD™ PAG1P will wait TAR sec before doing a soft start. This sequence is repeated

continuously (see Figure 5).

2. Latch or shutdown: No auto-restart timer or soft start is implemented. Shuts the IC immediately and power to

the IC needs to be removed to unlatch.

3. Gate OFF: This only turns OFF the gate drive pulse and waits for the fault condition to pass before the IC

functions normally.

4. Max duty cycle: Gate driver will be ON for 19 µs (maximum) during soft-start. When secondary is in control, gate

drive will be ON for 25 µs (maximum).
