2 / 22 page 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 • 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 1.2 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.
