TPS65178RSLR

Power Management - Specialized Overview

The TPS65178RSLR is a specialized power management IC designed for LCD bias applications, housed in a VQFN-48 package. It integrates multiple converters to support TFT-LCD panels, including a boost converter with an output range of 12.8V to 19V and two synchronous buck converters (Buck 2 and Buck 4) operating at frequencies exceeding 3MHz. The device features a non-synchronous Buck 1 with a 3.0V to 3.7V output range and fixed 600kHz frequency. Input voltage ranges from 8.6V to 14.7V, with a quiescent current of 5.5mA. It operates within a temperature range of -40°C to +85°C.
