1 / 29 page LMZ23608 www.ti.com SNVS708D – MARCH 2011 – REVISED OCTOBER 2011 LMZ23608 8A SIMPLE SWITCHER® Power Module with 36V Maximum Input Voltage and Current Sharing Check for Samples: LMZ23608 1 FEATURES APPLICATIONS 2 • 40W maximum total output power • Point of load conversions from 12V and 24V input rail • Up to 8A output current • Time critical projects • Input voltage range 6V to 36V • Space constrained / high thermal requirement • Output voltage range 0.8V to 6V applications • Efficiency up to 92% • Negative output voltage applications (See AN- 2027) DESCRIPTION The LMZ23608 SIMPLE SWITCHER© power module is an easy-to-use step-down DC-DC solution capable of driving up to 8A load. The LMZ23608 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering. The LMZ23608 can accept an input voltage rail between 6V and 36V and deliver an adjustable and highly accurate output voltage as low as 0.8V. The LMZ23608 only requires two external resistors and three external capacitors to complete the power solution. The LMZ23608 is a reliable and robust design with the following protection features: thermal shutdown, input under-voltage lockout, output over-voltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output. The sync input allows synchronization over the 350 to 600 kHz switching frequency range. Key Features • Integrated shielded inductor • Simple PCB layout • Frequency synchronization input (350 kHz to 600 kHz) • Current sharing capability • Flexible startup sequencing using external soft-start, tracking and precision enable • Protection against inrush currents and faults such as input UVLO and output short circuit • – 40°C to 125°C junction temperature range • Single exposed pad and standard pinout for easy mounting and manufacturing • Fully enabled for Webench® Power Designer • Pin compatible with LMZ22010/08, LMZ12010/08, LMZ23610/06H, and LMZ13610/08/06H 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
