Upgrade to myMPS+Product Description
The EVQ2459-J-00A is an evaluation board for the MPQ2459, a fixed 480kHz frequency step-down switching regulator with an integrated high-side high voltage power MOSFET.
The board can provide the load current up to 0.6A. High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition. The 5V to 55V input range accommodates a variety of step-down applications.
The board provides compact arrangement of components. By switching at 480kHz, smaller value inductor and input/output capacitor can be used to lower down cost and save board space.

IC Details
The MPQ2459 is a monolithic, step-down, switch-mode converter with a built-in power
MOSFET. It achieves a 0.5A peak output current over a wide input-supply range with
excellent load and line regulation. Current mode operation provides a fast transient response
and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal
shutdown. The MPQ2459 requires a minimal number of readily-available, standard, external components. The MPQ2459 is available in a TSOT23-6 package.
