... DS31191 150KHz, 5A PWM BUCK DC/DC CONVERTER General Description The AP1501A series are monolithic ICs that are designed for a step-down DC/DC converter, and possess the ability to drive a 5A load without additional transistor component. Due to reducing the number of external component, the board space can be saved easily ...

... ON/OFF pin can be wired to the ground pin or it can be left open, in either case the regulator will be in the ON condition. Thermal Considerations The AP1501A is available in two packages, a 5-pin surface mount TO-263 and TO-220. The TO-220 package needs a heat sink under most conditions. The size of the heat sink depends on the input voltage, the output voltage, the load current and the ambient temperature ...
