LM5025D PWM Controller

The LM5025D is a functional variant of the LM5025 active clamp PWM controller. The functional differences of the LM5025D are: • The CS1 and CS2 absolute maximum ratings have been increased to 7 V. • The CS1 and CS2 current limit thresholds have been increased to 0.5 V. • The internal CS2 filter discharge device has been disabled and no longer operates each c.
