Product details

Description

The PT1115 is a low cost, high efficiency pulse-width modulated (PWM) switching mode buck converter with both constant voltage (CV) and constant current (CC) functions.

The input voltage of PT1115 can be as high as 35V at which the over-voltage protection is triggered.
