Using LMZ31506HEVM-692, LMZ31503EVM-692 and LMZ31506EVM-692 Evaluation Module User's Guide Literature Number: SNVU295 JULY 2013 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. 1.1 Features • • • • 1.2 Complete Integrated Power Module Allows Small Footprint, Low-Profile Design Efficiencies Up To 96% Wide-Output Voltage Adjust 0.6 V to 5.5 V, with 1% Reference Accuracy Adjustable Switching Frequency 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. Table 1.

The EVM is set for a slow start time of 2.8 ms, (C8 = 4700 pF and J10 installed). 3.4 Track In The LMZ31506H, LMZ31503, and LMZ31506 can track an external voltage during start-up. The J6 connector is provided to allow connection to an external voltage. Ratio-metric or simultaneous tracking can be implemented using the provided resistor dividers with J5. See the product data sheet for details. 3.5 Adjustable UVLO The undervoltage lockout (UVLO) can be adjusted as described in the LMZ31506H, LMZ31503 and LMZ31506 data sheets. The EVM provides two selectable UVLO setpoints using the provided resistor dividers and J8. J9 provides an inhibit input. 3.6 Input Voltage Rails The EVM is designed to accommodate different input voltage levels for the power stage and control logic. During normal operation, the PVIN and VIN inputs are connected using a jumper across the top two pins of J3 (VIN = PVIN position). The single input voltage is supplied at J1. If desired, input voltage may be separated by moving the J3 jumper to the lower two pins (VIN = VBIAS position). Dual input voltages must then be provided at both J1 and J2. 4 LMZ31506H, LMZ31503 and LMZ31506 Simple Switcher® Power Module Evaluation Module Copyright © 2013, Texas Instruments Incorporated SNVU295 – JULY 2013 Submit Documentation Feedback TEST SET-UP www.ti.com 4 TEST SET-UP This section describes how to properly set-up and use the LMZ3150xEVM-692 evaluation module. 4.1 Input/Output Connections The LMZ3150xEVM-692 is provided with input/output connectors and test points as shown in Table 4.
