TLVM13660 36-V, 6-A Buck Regulator Evaluation Module 
User's Guide

ABSTRACT

With an input operating voltage range from 3 V to 36 V and rated output current from 2 A to 6 A, the 
TLVM13620, TLVM13630, TLVM13640, and TLVM13660 family of synchronous buck power modules outlined 
in 

Table 1-1

 provides flexibility, scalability, and optimized solution size for a wide range of applications. With 

intergrated power MOSFETs, buck inductor, and PWM controller, these modules enable DC/DC solutions with 
high density, low EMI, and increased flexibility. Available EMI mitigation features include RBOOT-configured 
switch-node slew rate control and integrated capacitors for the high-frequency switching loops. All modules are 
rated for ambient and junction temperatures up to 105°C and 125°C, respectively.

The 

TLVM13660EVM

 uses the TLVM13660 – a compact, easy-to-use synchronous buck module IC with a wide 

output voltage range of 1 V to 6 V and an output current up to 6 A. The default output voltage of the EVM is 5 V 
and is adjustable using jumper settings to the following output voltages as needed:

• 1.2 V
• 1.8 V
• 2.5 V
• 3.3 V

The solution supports adjustable input voltage UVLO for application-specific power-up and power-down 
requirements, a PGOOD indicator for sequencing and output voltage monitoring, and integrated VIN, VCC, 
and CBOOT capacitors for low EMI signature.
