- Technical Datasheet:
- MP4315GRE-P Datasheet
Product Overview
MP4315 is a synchronous step-down switching converter with a configurable frequency, as well as an integrated internal highside MOSFET (HS-FET) and low-side MOSFET (LS-FET). The device provides up to 5A of highly efficient output with current mode control for fast loop response. The wide 3.3V to 45V input voltage range accommodates a variety of step-down applications in automotive input environments. The MP4315's low 1.7µA shutdown mode quiescent current makes the device well-suited for battery-powered applications. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency under light-load conditions to reduce the switching and gate driver losses. An open-drain power good signal indicates whether the output is within 93% to 106% of its nominal voltage. It is available in a QFN-20 (4mmx4mm) wettable flank package. Applications include radios, battery power systems, general purpose consumer applications and industrial power systems.
- 18µA sleep mode quiescent current
- Internal 48mohm high-side MOSFET and 20mohm low-side MOSFET
- 350KHz to 1000KHz configurable switching frequency for car battery applications
- 100ns minimum on time, can be synchronized to an external clock
- Out-of-phase synchronized clock output, frequency foldback
- Frequency spread spectrum (FSS) for low EMI
- Symmetric VIN for low EMI, power good output, external soft start, thermal shutdown
- High-duty cycle and low-dropout mode are provided for the automotive cold crank conditions
- Selectable advanced asynchronous mode or forced continuous conduction mode (FCCM)
- Low-dropout mode, hicc-up overcurrent protection
