AP1501A-12K5L-U Datasheet PDF - Diodes

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. The external shutdown function can be controlled by logic level and then come into standby mode.

●Features

●• Output voltage: 3.3V, 5V, 12V and adjustable output version

●• Adjustable version output voltage range, 1.23V to 37V+4%

●•150Khz +15% fixed switching frequency

●• Voltage mode non-synchronous PWM control

●•Thermal-shutdown and current-limit protection

●• ON/OFF shutdown control input

●• Operating voltage can be up to 40V

●• Output load current: 5A

●• Low power standby mode

●• Built-in switching transistor on chip

●• Lead Free packages: TO263-5L and TO220-5L(R)

●• TO263-5L and TO220-5L(R): Available in “Green” Molding Compound (No Br, Sb) 

●• Lead Free Finish/ RoHS Compliant (Note 1)

●Applications

●• Simple High-efficiency step-down regulator

●• On-card switching regulators

●• Positive to negative converter
