Product Overview
MPQ4312 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 provides up to 2A of highly efficient output current (IOUT) with current mode control for fast loop response. The wide 3.3V to 45V input voltage (VIN) range accommodates a variety of step-down applications in automotive input environments. High power conversion efficiency across a wide load range is achieved by scaling down the switching frequency (fSW) under light-load conditions to reduce the 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. Frequency foldback helps prevent inductor current runaway during start-up. Applications include automotive infotainment, automotive clusters, advanced driver assistance systems (ADAS) and industrial power systems.
- 18µA sleep mode quiescent current, 1.7µA shutdown mode quiescent current
- Internal 48mohm high-side and 20mohm low-side MOSFETs
- 350KHz to 1000KHz configurable switching frequency (fSW) for car battery applications
- Synchronizable with external clock, out-of-phase synchronized clock O/P, AEC-Q100 grade 1 qualified
- Frequency spread spectrum (FSS) for low EMI
- Symmetric VIN for low EMI, power Good (PG) output, external soft start (SS)
- 100ns minimum on time, low-dropout mode, hiccup overcurrent protection (OCP)
- Selectable advanced asynchronous mode (AAM) or forced continuous conduction mode (FCCM)
- Thermal shutdown provides reliable, fault-tolerant operation, available in a QFN-20 (4x4mm) package
- High-duty cycle and low-dropout mode are provided for automotive cold-crank conditions
