Description
General part information
LMR43620-Q1 Series
The LMR436x0-Q1 is the industry smallest 36V, 2A, and 1A synchronous step-down DC/DC converters in a 2mm × 2mm HotRod package. This easy-to-use converter supports a wide input voltage range of 3.0V to 36V with transients up to 42V.
The LMR43620-Q1 is specifically designed to meet low standby power requirements for always on, automotive applications. Auto mode enables frequency foldback when operating at light loads, allowing an unloaded current consumption of 1.5µA at 13.5VIN and high light load efficiency. A seamless transition between PWM and PFM modes along with very low MOSFET ON resistances provide exceptional efficiency across the entire load range.
The control architecture and feature set are designed for an ultra-small design size. The device uses peak current mode control to minimize output capacitance. The LMR436x0-Q1 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 200kHz and 2.2MHz to avoid noise sensitive frequency bands.
