The LMR436x0 is the industry smallest 36-V, 2-A, and 1-A synchronous step-down DC/DC converters in a 2-mm × 2-mm HotRod package. This easy-to-use converter supports a wide input voltage range of 3.0 V to 36 V with transients up to 42 V.
The control architecture and feature-set are optimized for an ultra-small solution size. The device uses peak current mode control to minimize output capacitance. The LMR436x0 minimizes input filter size by using dual random spread spectrum, a low-EMI HotRod package, and an optimized pinout. The MODE/SYNC and RT pin variants can be used to set or synchronize the frequency between 200 kHz and 2.2 MHz to avoid noise sensitive frequency bands.
The compact solution size and rich feature set of LMR436x0 simplifies implementation for a wide range of industrial applications.
