Introduction
The PE25200 is an ultra-high efficiency DC-DC converter solution that divides down an input voltage by either a
factor of 2 or 3 and delivers up to 45W output at up to 95.4% peak efficiency. The PE25200 supports an input
voltage range of 15V max in divide

2 mode and is available in a WLCSP
package.
Evaluation Kit Overview
The PE25200 evaluation kit (EVK) is a hardware platform that allows customers to test the step-down DC-DC
converter. High-current connections are via 4 mm sockets (banana plug style) with test hoops for connecting
sensing and test equipment probes. A number of customer-adjustable links can be used to invoke alternate
operational modes.

Table 1. Evaluation Kit Contents
Hardware Requirements
In order to evaluate the performance of the evaluation board, the following equipment is required:
■
Bench supply capable of providing 10V–15V at 5A minimum with sense lines
■
Two digital multi-meters
■
Four-channel oscilloscope with probes (optional to view waveforms)
■
Electrical load
Caution
: The PE25200 DC-DC converter EVK contains components that might be damaged by exposure to
voltages in excess of the specified voltage, including voltages produced by electrostatic discharges. Handle the
board in accordance with procedures for handling static-sensitive components. Avoid applying excessive voltages
to the power supply terminals or signal inputs or outputs.
In particular, note that the
input is at the bottom of the board marked in bold GND and VIN.
When connecting the EVK to the source power supply, ensure the power supply is off. Connecting the EVK to a
live power supply unit may cause failures. Ensure the output load is disconnected.
