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
