User's Guide
SNVU295 – JULY 2013
LMZ31506H, LMZ31503 and LMZ31506
Simple Switcher® Power Module Evaluation Module
This user's guide contains background information for the LMZ31506H, LMZ31503, and LMZ31506 and
support documentation for the LMZ31506HEVM-692, LMZ31503EVM-692 and LMZ31506EVM-692
evaluation module (LMZ3150xEVM-692).
1
Introduction
The LMZ31506H & LMZ31506 Simple Switcher® power modules provide up to 6-A of output current and
the LMZ31503 provides up to 3-A of output current. These power modules have dual-voltage inputs for the
power stage and control circuitry. The power stage input (PVIN) is rated for 1.6 V to 14.5 V whereas the
control input (VIN) is rated for 4.5 V to 14.5 V. The LMZ3150xEVM-692 provides both inputs but is
designed and tested with PVIN connected to VIN. Rated input voltage and output current range for the
evaluation module are given in Table 1.

Background
This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be
achieved when designing with the LMZ31506H, LMZ31503, and LMZ31506 power modules. The high-side
and low-side MOSFETs are incorporated inside the device's package along with the gate drive circuitry.
The low drain-to-source on-resistance of the MOSFET allows the LMZ31506H, LMZ31503, and LMZ31506
to achieve high efficiencies and helps keep the junction temperature low at high output currents. The
compensation components are internal to the device, and external resistors and jumpers allow for
adjustable output voltage and frequency adjustment. Additionally, the LMZ31506H, LMZ31503, and
LMZ31506 provide adjustable slow start, tracking, and undervoltage lockout inputs. The absolute
maximum input voltage is 15 V.
