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
