LNBH26LPQR ST Power Management IC | 24-VFQFN Exposed Pad | 1.8V Logic, I2C Control

Product Overview

The LNBH26LPQR is a monolithic voltage regulator and interface IC designed for satellite LNB (Low Noise Block) power supply and control. Manufactured by STMicroelectronics, this device integrates a step-up DC-DC converter, a linear regulator, and an I2C interface to provide a complete solution for powering and controlling LNBs in satellite TV and VSAT systems. It operates from a single 3.3V or 5V supply and delivers a programmable output voltage from 8V to 14V with up to 500mA output current. The 24-VFQFN package with exposed pad ensures excellent thermal performance.
