Evaluates: MAX17552/MAX17552B (TDFN)

in 5V Output Voltage Applications

MAX17552 5V Output

Evaluation Kit (TDFN)

General Description

Quick Start

The MAX17552 5V evaluation kit (EV kit) (TDFN) is a fully

assembled and tested circuit board that demonstrates the

performance of the MAX17552 60V, 100mA ultra-small,

high-efficiency, synchronous step-down DC-DC converter

in a 10-pin TDFN package. The EV kit operates over a

wide input-voltage range of 6V to 60V and provides up

to 100mA load current at 5V output. It draws only 26µA

supply current under no-load conditions (EN/UVLO con-

nected to V ). The EV kit is programmed to switch at a

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation. Caution: Do not turn on

the power supply until all connections are completed.

frequency of 220kHz and delivers a peak efficiency of

93% with the supplied components. The device is simple

to use and easily configurable with minimal external

components. It features cycle-by-cycle peak current limit

protection, undervoltage lockout, and thermal shutdown.

1) Verify that shunts are installed on jumpers JU1, JU2

(EN/UVLO).

2) Verify that jumper JU3 (MODE-PFM operation) is open.

The EV kit comes installed with the MAX17552ATB+ in

an 10-pin (3mm x 2mm) lead(Pb)-free/RoHS-compliant

TDFN package.

3) Set the electronic load to constant-current mode,

100mA, and disable the electronic load.

4) Connect the electronic load’s positive terminal to the

VOUT PCB pad. Connect the negative terminal to

the GND PCB pad.

Features and Beneﬁts

● 6V to 60V Input Voltage Range

● 5V Output, 100mA Continuous Current

● 93% Peak Efficiency

5) Connect the voltmeter across the VOUT and GND

PCB pads.

6) Set the power-supply output to 24V. Disable the

power supply.

● 26µA No Load Supply Current

● EN/UVLO for On/Off Control and Programmable

7) Connect the power-supply output to the VIN PCB pad.

Connect the supply ground to the GND PCB pad.

Input Undervoltage Lockout

● Programmable Switching Frequency

● Internal or Programmable Soft-Start

● PFM or Forced-PWM Mode of Operation

● Open-Drain RESET Output

● Peak Current Limit Protection

● Thermal Shutdown

8) Turn on the power supply.

9) Enable the electronic load and verify that output volt-

age is 5V with respect to GND.

10) Vary the input voltage from 6V to 60V.

11) Vary the load current from 1mA to 100mA and verify

that output voltage is 5V with respect to GND.

Note: While performing an output short-circuit test, it is

possible for the ceramic output capacitor to oscillate with

the wiring inductance between the capacitor and short-

circuited load, and thereby cause the absolute maximum

pin (-0.3V) to be exceeded. The

resistor (R7) and the capacitor (C5) are included on this

evaluation kit to protect against unintentional violation of

the above mentioned rating. In the actual system design,

parasitic board or wiring inductance should be minimized

and the output-voltage waveform under short-circuit

operation should be verified to ensure that the absolute
