MP4316GRE-P, Switching Voltage Regulators 45V, 6A, Low Iq Synchronous Step-DownConverter with Frequency Spread Spectrum
Semiconductors\Power Management ICs\Voltage Regulators & Voltage Controllers\Switching Voltage Regulators
MP4316 is a frequency-configurable, 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 6A 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. The MP4316 provides high power conversion efficiency across the entire load range. Advanced asynchronous modulation (AAM) mode achieves high efficiency under light-load conditions by scaling down the switching frequency (fSW) to reduce the switching and gate driver losses. MP4316 is available in a QFN-20 (4mmx4mm) package. 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
• External SYNC 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 enable the device to withstand automotive cold-crank conditions
• Open-drain power good signal indicates whether output is between 95% and 105% of its nominal voltage
