HM2459 Overview
The HM2459 is a wide input range, high-efficiency, and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 1.5A of output current. With a fixed switching frequency of 650KHz, this current mode PWM controlled converter allows the use of small external ponents, such as ceramic input and output caps, as well as small inductors.HM2459 also employs a proprietary control scheme that switches...
