PRODUCTION DATA. LMZ34202 SNVSAJ2 – MARCH 2016 LMZ34202 SIMPLE SWITCHER 4.5-V to 42-V Input, 2-A Power Module 1 1 Features 1 • Complete Integrated Power Solution Allows Small Footprint, Low-Profile Design • 10 mm × 10 mm × 4.3 mm Package • Wide-Output Voltage Adjust (2.5 V to 7.5 V) • Adjustable Switching Frequency (200 kHz to 1 MHz) • Synchronizes to an External Clock • Automatic PFM Mode for Light Load Efficiency • Adjustable Soft-Start Time • Output Voltage Sequencing / Tracking • Power Good Output • Programmable Undervoltage Lockout (UVLO) • Over-Temperature Thermal Shutdown Protection • Over-Current Protection (Hiccup Mode) • Pre-Bias Output Start-Up • Operating Temperature Range: –40°C to 105°C • Enhanced Thermal Performance: 14°C/W • Meets EN55022 Class B Emissions – Integrated Shielded Inductor 2 Applications • Industrial and Motor Controls • Automated Test Equipment • Medical and Imaging Equipment • High Density Power Systems 3 Description The LMZ34202 SIMPLE SWITCHER® power module is an easy-to-use integrated power supply that combines a 2-A DC-DC converter with a shielded inductor and passives into a low profile, QFN package. This total power solution allows as few as three external components while maintaining an ability to adjust key parameters to meet specific design requirements. The QFN package is easy to solder to a printed circuit board, allows reflow profiles up to 260°C, and has excellent power dissipation capability. The LMZ34202 offers flexibilty with many features and is ideal for powering a wide range of devices and systems. Device Information(1) DEVICE NUMBER PACKAGE BODY SIZE LMZ34202 QFN (43) 10.0 mm × 10.0 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
