34717 Datasheet | Freescale Semiconductor

Freescale Semiconductor Advance Information 5.0 A 1.0 MHz Fully Integrated Dual Switch-Mode Power Supply Document Number: MC34717 Rev 5.0, 12/2014 The 34717 is a highly integrated, space-efficient, low cost, dual synchronous buck switching regulator with integrated N-channel power MOSFETs. It is a high performance dual point-of-load (Po L) power supply with many desired Features for the 3.3 and 5.0 V environments. Both channels can provide up to 5.0 A of continuous output current capability with high efficiency and tight output regulation. The second channel has the ability to track an external reference voltage in different configurations. The 34717 SMARTMOS device offers the designer the flexibility of many control, supervisory, and protection functions to allow for easy implementation of plex designs. It is housed in a Pb-free, thermally enhanced, and space efficient 26 pin exposed pad QFN. Features - 50 m integrated N-channel power MOSFETs - Input voltage operating range from 3.0 to 6.0 V - 1% accurate output voltages, ranging from 0.7 to 3.6 V - The second output has voltage tracking capability in different configurations - Programmable switching frequency range from 200 k Hz to 1.0 MHz - Programmable soft start timing - Over-current limit and short-circuit protection - Thermal shutdown - Output overvoltage and undervoltage detection - Active low power good output signal - Active low shutdown input.
