4.5-V to 24-V, 8-A synchronous step-down voltage regulator

Overview

TopologyBuck Converter
Input voltage4.5-24 V
Output 18 A

Description

The TPS51396AEVM evaluation module (EVM) is used to evaluate the TPS51396A, a high-voltage input, high-efficiency synchronous buck converter with integrated FETs. The key feature of the TPS51396A is its ULQ™ (ultra low quiescent), which enables low-bias current and large duty operation. The ULQ feature is extremely beneficial for long battery life in low-power operation. The TPS51396A operates with a supply input voltage ranging from 4.5 V to 24 V. It uses DCAP3™ control mode to provide a fast transient response, good line, load regulation, no requirement for external compensation and supports low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors. The TPS51396A provides OVP, UVP, OCP, OTP and UVLO. TPS51396A also has combined power good signal and output discharge function.
