Product Overview
MP4317 is a configurable-frequency, synchronous, step-down switching converter with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It can achieve up to 7A of highly efficient, continuous output current (IOUT) with current control mode for fast loop response. The wide 3.3V to 45V input voltage (VIN) range accommodates a variety of step-down applications in an automotive input environment. The device's 1.7µA shutdown current (ISD) makes it ideal for battery-powered applications. High power conversion efficiency across the entire load range is achieved by scaling down the switching frequency (fSW) under light-load conditions. This reduces switching and gate driver losses. An open-drain power good (PG) signal indicates whether the output is within 95% to 105% of its nominal voltage. Applications include radios, battery-powered systems, general-purpose consumer applications and industrial power systems.
- 18µA sleep mode quiescent current (IQ), internal 48mohm and 20mohm power MOSFETs
- 350KHz to 1000KHz configurable switching frequency (fSW) for car battery applications
- Can be synchronized to an external clock, out-of-phase synchronized clock output
- Frequency spread spectrum (FSS) for low electromagnetic interference (EMI)
- Symmetric VIN for low EMI, power good (PG) output, external soft start (SS)
- 100ns minimum on time (tON
- MIN), low-dropout (LDO) mode, overcurrent protection with hiccup mode
- Selectable advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM)
- Frequency foldback thermal shutdown for reliable, fault-tolerant operation
- High duty cycle and low-dropout mode are provided for automotive cold-crank conditions
- Available in a QFN-20 (4mmx4mm) package
