MPQ2918 - Step-Down Controller

General Description

The MPQ2918 is a high-voltage, synchronous, step-down controller that steps down voltages directly from up to 40V.

The MPQ2918 uses pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual N-channel MOSFETs.

Key Features

  • include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown. The MPQ2918 is available in TSSOP-20EP and QFN-20 (3mmx4mm) packages. MPQ2918 4V - 40V Input, Current Mode, Synchronous, Step-Down Controller AEC-Q100 Qualified.

DESCRIPTION The MPQ2918 is a high-voltage, synchronous, step-down controller that steps down voltages directly from up to 40V. The MPQ2918 uses pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual N-channel MOSFETs. Advanced asynchronous mode (AAM) enables non-synchronous operation to optimize lightload efficiency. The operating frequency of the MPQ2918 can be programmed by an external resistor or synchronized to an external clock for noisesensitive applications. Full protection features include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown. The MPQ2918 is available in TSSOP-20EP and QFN-20 (3mmx4mm) packages.
