- Synchronizable to external clock
- Internal compensation
- Power-good flag
- Precision enable to program system UVLO
- Flexible soft-start features:
- Start-up into pre-biased load
- Fixed or adjustable soft-start time
- Output voltage tracking
- Cycle-by-cycle current limiting
- Short-circuit protection with hiccup mode
- Create a custom design with the WEBENCH® power designer using LM73605 or LM73606
The LM73605 and LM73606 family of devices are easy-to-use synchronous step-down DC/DC converters capable of driving up to 5 A or 6 A of load current from a supply voltage ranging from 3.5 V to 36 V. The LM73605 and LM73606 provide exceptional efficiency and output accuracy in a very small solution size. Peak current-mode control is employed. Additional features such as adjustable switching frequency, synchronization to an external clock, power-good flag, precision enable, adjustable soft start, and tracking provide both flexible and easy-to-use solutions for a wide range of applications. Automatic frequency foldback at light load improves efficiency over the entire load range. Protection features include thermal shutdown, cycle-by-cycle current limiting, and short-circuit protection. The devices are pin-to-pin compatible for easy current scaling. The new product, LM61460-Q1, offers higher efficiency, lower stand-by quiescent current, and improved EMI performance. See the device comparison table to compare specifications. Start a Webench design with LM61460-Q1. Use the LMZM33606 module for faster time to market.
