Pcb temperature
The PKB series of high efficiency DC/DC converters
are designed to provide high quality on-board power
solutions in distributed power architectures used in
Internetworking equipment in wireless and wired
communications applications. The PKB 4000 series
has industry standard footprint and pin-out and is only
7.62 mm (0.30 in) high. This makes it extremely well
suited for narrow board pitch applications with board
spacing down to 15 mm (0.6 in). Included as standard
features are output over-voltage protection, input
under-voltage protection, over temperature protection,
soft-start, output short circuit protection, remote sense,
remote control and output voltage adjust function.
These converters are designed to meet high reliability
requirements and are manufactured in highly automated
manufacturing lines and meet world-class quality levels.
Ericsson Power Modules is an ISO 9001/14001 certified
supplier.
