Evaluation Module Overview
1 Evaluation Module Overview
1.1 Introduction
The TPSM64406 is a highly integrated 36V input capable, DC/DC design that combines power MOSFETs,
a shielded inductor, and passives in an enhanced HotRod
output or high current single output using an interleaved, stackable, current-mode control architecture for easy
loop compensation, fast transient response, excellent load and line regulation, and accurate current sharing
with an output clock supporting up to 6 phases for currents up to 18A. The module has VIN and VOUT pins
located at the corners of the package for optimized input and output capacitor placement. A large thermal pad
beneath the module enable a simple layout and easy handling in manufacturing. With an output voltage from
1V to 16iV, the TPSM64406 is designed to quickly and easily implement a low-EMI design in a small PCB
footprint. The total design requires as few as six external components and eliminates the magnetics selection
from the design process. Although designed for small size and simplicity in space-constrained applications, the
TPSM64406 module offers many features for robust performance: precision enable with hysteresis for adjustable
input voltage UVLO, and spread spectrum for improved EMI. Along with integrated VCC, bootstrap and input
capacitors for increased reliability and higher density. The module can be configured for constant switching
frequency over the full load current range (FPWM), or variable frequency (PFM) for higher light load efficiency,
including a PGOOD indicator for sequencing, fault protection, and output voltage monitoring.

Full-load efficiency
(1) Default output voltages and switching frequency are 5V or 3.3V selectable and 1MHz, respectively.
(2) The recommended airflow is 200 LFM when operating
(3) The EVM operates when the input voltage is in the range of 3V to 6V, but enters a dropout mode if there is insufficient input voltage to
regulate output voltages.
