Enpirion Inc. (Bloomsbury, NJ), a developer of power management solutions based on its proprietary Power System on a Chip (PSoC) technology, announced its new EN5330 Power System on a Chip (PSoC) and synchronous buck converter. The EN5330 is the first of the iPOWER™ line of integrated dc-dc converters for use in point-of-load (POL) applications, including servers, personal computers, laser printers, set-top boxes, and telecommunications and data communications equipment.
The EN5330 is in a dual flat no-lead (DFN) TSSOP footprint package that covers just over 100 mm² of board space. Including the minimum of three external components, the entire dc-dc converter can be placed in as little as 135 mm² of single-sided, or 102 mm² of double-sided board space. Combined with a height profile of 2.2 mm and efficiencies up to 90 percent, the EN5330 offers operation from common voltage rails of 2.5 V, 3.3 V and 5 V, with a wide input-voltage range from 2.375 V to 6.5 V. With up to 3 A or 10 W of output power, the output voltage is VID pin selectable with options for seven standard voltages (0.8 V to 3.3 V) and a resistor divider setting enabling a continuous set-point range from 0.8 V to Vin. Full protection functionality is offered with over-current, short-circuit, over-voltage, under-voltage and thermal shutdown features.
The EN5330 is available now in standard and lead-free package options. Pricing is $4.95 each for orders in 1,000-unit quantities, and product evaluation boards are available.
