iP1203, iPOWIR Building Block
for Single Phase Buck Converters
The iP1203 power 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 telecommunication systems. The iP1203 is ideal 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 iP1203 building block integrates a
full-function PWM control IC, trench MOSFETs and passive components enabling
excellent thermal performance at raised ambient temperature without de-rating.
The iP1203 is a fully-optimized, full-function 15A single output synchronous buck
converter device that achieves over 90% efficiency at full load, addressing
requirements from 5.5Vin to 13.2Vin and 0.8Vout
to 8Vout, while maintaining a full load capability of 15A.
