Integrated 'building block' power converter delivers 15 A
15 June 2005
Power Electronics / Power Management
International Rectifier has introduced a fully-optimised, full-function 15 A single output synchronous buck converter device that it says achieves over 90% efficiency at full load. The iPOWIR iP1203 is a flexible solution that addresses requirements from 5,5 Vin to 13,2 Vin and 0,8 Vout to 8 Vout, maintaining a full load capability of 15 A.
The iP1203 building block is designed to simplify DC-DC point-of-load (POL) converters for network processor units (NPUs) and ASIC power rails within networking and telecom systems. It is well suited for use in two-stage distributed power architectures being fed from either a regulated isolated brick or an unregulated DC bus converter.
Offering superior power density, the device integrates a full-function PWM control IC, trench MOSFETs and passive components enabling superior thermal performance at raised ambient temperature without de-rating.
The iP1203 addresses important networking and telecom power system requirements such as hiccup over-current, over-temperature and over-voltage protection, external synchronisation, power good and soft start. The building block is housed in an LGA package (9 x 9 x 2,3 mm).
