1.1 Introduction

This user's guide describes the setup, schematic, and layout of the evaluation module (EVM) for the TPS61377. The EVM helps to evaluate the behavior and performance of the device at different input voltages, output voltages, and load conditions.

This EVM is designed for 9 V to 16 V input voltage and 24 V output voltage applications. The MODE jumper (J6) controls the operating mode of the device. When MODE is connected to H, the device operates in forced PWM mode; when MODE is connected to L, the device operates in auto PFM mode. This EVM has test points of TP5 and SW for loop and SW voltage measurement, respectively. The peak current limit can be set from 1.5 A to 6 A by changing the resistance of RLIM (R6) from 57.6 kΩ to 14.4 kΩ. The feedback divider and compensation network can be modified for other application conditions as per the data sheet.
