EVM54504-BS-00A
5A, 16V, 4-Channel Ouput, Step-Down Power
Module with Internal Auto-Compensation
Evaluation Board
DESCRIPTION
FEATURES
The EVM54504-BS-00A is an evaluation board
designed to demonstrate the capabilities of the
MPM54504, a four-channel output, step-down
power module. Each channel can deliver up to
5A of continuous output current across a wide
input voltage range (3V to 16V), with excellent
load and line regulation. The MPM54504
integrates monolithic power stages and
inductors that support passive components to
achieve high efficiency.
The MPM54504 features internal autocompensation, and does not require any
external compensation components.
Constant-on-time (COT) control provides fast
load transient response, simple loop design,
and tight output regulation.
The MPM54504’s protection features include
short-circuit protection (SCP), over-current
protection (OCP), over-voltage protection
(OVP), under-voltage protection (UVP), overtemperature protection (OTP), and thermal
shutdown (TSD).
APPLICATIONS
The MPM54504 is available in a FCMBGA
(9mmx15mmx5mm) package.

QUICK START GUIDE
1. Preset the power supply between 3V and 16V, then turn off the power supply.
2. Connect the power supply terminals to:
a. Positive (+): VIN
b. Negative (-): GND
3. Connect the load terminals (≤5A) of channels 1, 2, 3, and 4 to:
a. Positive (+): VOUT
b. Negative (-): GND
4. After making the connections, turn on the power supply. The board should automatically start up.
