3peak incorporated TPP2020

17-V Input, 2-A Synchronous Step-Down Voltage Regulator

Overview

TopologyBuck-Boost Converter
Input voltage4.5-17 V
Output 17 V / 2 A

Description

The TPP2020EVM evaluation module helps designer evaluate the operation and performance of the TPP2020. The TPP2020 dc/dc synchronous converter is designed to provide up to a 2 A output from an input source of 4.5V to 17V. The output v oltage range is from 0.768 V to 7 V. Output voltages can be changed by changing the feedback resistors.
