DESCRIPTION The MPQ4371 family of buck converters are configurable-frequency (200kHz to 2.5MHz), synchronous, step-down switching regulators with integrated low on-resistance HS-FETs and LS-FETs. The family covers a 6A to 11A output current (IOUT) range and employs zero-delay PWM (ZDP™) control, an MPS-exclusive technology that delivers fast transient response while reducing external capacitor count. The wide 3.3V to 36V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environment. A 1.8μA shutdown mode quiescent current allows use in battery-powered applications.
