PMA 8811 SF DC/DC regulator 12V / 5V at 16A Key Features * Surface mountable * Low profile, max 8.5mm (0.33 in) * High efficiency * Low weight * Designed For Environment, DfE * Lead-free / Bromine-free * Robust design * Over temperature protection * Power Good signal * Wide input, 9 - 16 V * Stable operation under all conditions The PMA series of DC/DC regulators (POL) are intended to be used as local distributed power sources in distributed power architecture level 4. The PMA series use a ceramic substrate with fine-pitch components technology and a high degree of silicon integration. Together with the electrical design using low Rds-On MOSFET, this provides excellent thermal management, high reliability and high efficiency. The high efficiency makes it possible to operate over a wide temperature range, without adding any external heat dissipator. At forced convection cooling >1 m/s (200 lfm), the PMA typically delivers full power up to +80 C ambient temperature. E The high reliability and the low profile of the PMA series makes them particularly suited for the communications equipment of today and tomorrow and applications with board spacing down to 15 mm (0.6 in). The flat case top enables pick-and-place handling and provides a surface for attachment to cooling surfaces in areas with limited air flow. These products are manufactured using the most advanced technologies and materials to comply with environmental requirements. Designed to meet high reliability requirements of systems manufacturers, the PMA responds to world-class specifications. Ericsson Power Modules is an ISO 9001/14001 certified supplier.
