製品説明

The MPQ2420 is a step-down switching regulator with integrated high- and low-side, high-voltage power MOSFETs. It provides a highly efficient output of up to 0.3A. The integrated watchdog adds additional security redundancy to the system. The wide 4.5V to 75V input range accommodates a variety of step-down applications in an automotive environment. A 5µA shutdown mode quiescent current in a full temperature range is ideal for battery-powered applications. It allows for high-power conversion efficiency over a wide load range by scaling down the switching frequency under a light-load condition to reduce switching and gate driver losses. The start-up switching frequency and short circuit can also be scaled down to prevent inductor current runaway. Full protection features include under-voltage lockout (UVLO) and thermal shutdown. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ2420 is available in a TSSOP-16 EP package.

75V, 0.3A, Synchronous Step-Down Converter with Watchdog Evaluation Board

The EV2420-F-00A is an evaluation board for the MP2420GF and MPQ2420GF, a synchronous step-down switching regulator with integrated high-side/low-side, high-voltage power MOSFETs. It provides a highly efficient output of up to 0.3A. The integrated watchdog adds additional security redundancy to the system.

It allows for high power conversion efficiency over a wide load range by scaling down the switching frequency under light-load conditions to reduce the switching and gate driver losses.

The EV2420-F-00A is assembled and tested with a TSSOP-16 EP package.
