... Philips Semiconductors SMPS control circuit One final point on the compensation terminal is that this is also a convenient place to insert any programming signal which is to override the error amplifier. Internal shutdown and current limit circuits are connected here, but any other circuit which can sink 200 A can pull this point to ground, thus shutting off both outputs ...
