Overview
AP1501 150KHZ, 3A PWM BUCK DC/DC CONVERTER Description The AP1501 is a fully integrated step-down DC/DC converter, with the ability to drive 3A load without the need of additional driver components.
The AP1501 operates at a switching frequency of 150kHz enabling the use of small size filter components.
As a result, board space is reduced and BOM costs are lowered.
The AP1501 has integrated the shutdown function that allows standby mode to be activated via an external logic signal input.
The internal compensation facilitates feedback control for line and load regulation without the need of an external circuitry.
The AP1501 has a built-in Thermal shutdown and Current Limit function to prevent damage from high operating temperature and high current operating to the output switch.
Additional features include a guaranteed +/- 4% tolerance on the output voltage under specified input and output load conditions, and +/- 15% on oscillator frequency.
The AP1501 offers both fixed and adjustable output voltages.
For fixed outputs the AP1501 supports 3.
3V, 5.
0V and 12V.
The package options available are standard 5lead TO263 and TO220 packages.
