SP6134HEU-L

SP6134H High Voltage, 600kHz Synchronous PWM Step Down Controller January 2020 Rev. 2.0.1 GENERAL DESCRIPTION APPLICATIONS • Wireless Base Station The SP6134H is a 600kHz constant frequency, voltage mode, synchronous PWM step down controller optimized for high efficiency. • Automotive • Industrial The SP6134H is adequately suited for split plane applications utilizing a low power 5V rail to power the controller circuitry, minimizing power dissipation. Its wide input voltage range of 3V to 15V allows for conversions from the standard 3.3V, 5V, 9.6V and 12V power rails to an output voltage adjustable down to 0.8V. Developed around a wide bandwidth internal amplifier, the SP6134H can accommodate type II and type III compensation schemes. • Power Supply FEATURES • 3V to 28V Step Down Achieved Using Dual Input • On-Board 1.5Ω sink (2Ω source) NFET Drivers • Up to 15A Output Capability Protection features include a programmable UVLO, thermal shutdown and output short circuit protection. • UVLO Detects Both VCC and VIN • Short-Circuit Protection with AutoRestart The SP6134H is part of a larger family of step down controllers operating at various switching frequencies up to 1300kHz and input voltages up to 28V. Refer to Exar’s SP6134, SP6132, SP6132H, SP6137 and SP6139 for complete details. • Supports Type II or III Compensation • Programmable Soft Start • Fast Transient Response • High Efficiency: Greater than 94% The SP6134H is available in lead free, RoHS compliant, space saving 10-pin MSOP package. • Non-synchronous Start-Up • Small 10-Pin MSOP Package • U.S. Patent #6,922,041 TYPICAL APPLICATION DIAGRAM Fig. 1: SP6134H Application Diagram 1/15 Rev. 2.0.1 SP6134H High Voltage, 600kHz Synchronous PWM Step Down Controller ABSOLUTE MAXIMUM RATINGS These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.
