Marvell^® DSP Switcher™ Power Management Family

Innovative Switching Regulators Based on DSP Architecture

Marvell DSP Switcher integrated regulator modules provide plug-and-play implementations of Marvell switching regulator IC’s in convenient, modular form factors. The same benefits in performance – efficiency, precision, transient response and small size – are preserved while providing a fully assembled, tested and guaranteed power supply. No design effort is needed to integrate Marvell switching regulator modules into your system – simply choose SIP, DIP or SMT form factors and provide a single programming resistor to set the desired output voltage. The full range of output voltages 0.72V to 3.63V is supported with one part number. Output current levels up to 10A are supported with input voltages of 3.0V-5.5V 8 to 14 volts.

The Marvell DSP Switcher™ module family of products are the industry’s highest-performance step-down DC-DC power modules. Each module is an application of the corresponding Marvell DSP Switcher regulator IC and are available in single output and dual output versions. They are suitable for a wide range of point-of-load (POL) applications while unparalleled precision, efficiency, transient response, and small size make these modules attractive for demanding loads such as DSP’s and ASIC’s.
