EVQ4316A-R-01A

EVQ4316A-R-01A is a 45V, 6A, Low-IQ, synchronous buck converter with a frequency spread spectrum evaluation board. This evaluation board is designed to demonstrate the capabilities of the MPQ4316A, a synchronous, step-down switching regulator with a configurable frequency and integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET). It provides up to 6A of highly efficient output current (IOUT) with current mode control for fast loop response. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce the switching and gate driver losses. Frequency foldback helps prevent inductor current (IL) runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. A high duty cycle and low-dropout mode are provided for automotive cold-crank conditions.
