This slide shows a few more parts in different packages with a different number of pins to support a different number of features. The AP63357 device is a 32V input, 3.5A output Buck converter with LDO Mode, FSS, and both a Compensation pin and PG pin. The AP62600 device is an 18V input, 6A output Buck converter. It has the ability to select its operation mode and switching frequency. It also has adjustable soft-start with a PG pin. The AP61102 is a 5.5V input, 1A output Buck converter. It is in a smaller package and has fewer pins than the other converters discussed but it still has a PG pin that can be used for power sequencing. It also has the ability to select its operation mode as PFM or Forced PWM through its Enable pin.
