"Most competitors ' half-bridge controllers require an external half-bridge
FET driver, which increases the solution footprint and introduces timing
errors due to propagation delays," said Paul Greenland, director of strategic
marketing for National Semiconductor's Power Management Group. National's innovative power management products include
best-in-class linear regulators; power monitoring, control and reference ICs;
and switching converters, such as high-voltage ICs for DC-DC conversion,
switched capacitor converters, lighting management ICs and inductive switching
converters. This
multi-foundry , multi-process PDK enables educational institutions and
fabless companies to be immediately productive in using Silvaco IC design
capture, simulation, layout and verification tools. "Our integrated Linux , Solaris, and PC-based tools enable our PDK
development team to rapidly deliver foundry-specific analog/mixed-signal/RF
PDKs for high-volume designs. The cost of fabricating prototype quantities is kept low by
aggregating multiple designs onto one mask set.

About MagnaChip Semiconductor
MagnaChip Semiconductor is a leading designer, developer and manufacturer
of mixed-signal and digital multimedia semiconductors addressing the
convergence of consumer electronics and communications devices. It also includes:
-- Synchronous rectifier controls with programmable delays that allow
users to optimize power efficiency by tuning the secondary-side and
primary-side FET switch timing
-- Voltage-mode control for stable operation in half-bridge topology and
better noise immunity than current mode control
-- Line feed-forward compensation to improve regulation during input line
voltage fluctuations
-- Resistor-programmed oscillator capable of operating up to 2 MHz
-- Synchronization capability to lock the PWM to an external oscillator
for reduced electro-magnetic interference
-- Programmable line under-voltage lockout to control power-on sequencing
and minimize start-up current surges
-- Remote thermal sensor interface that directly connects to an external
thermister
-- Adjustable soft-start for safe start-up in applications with large
capacitive loads
-- Versatile, dual-mode over-current protection with hiccup delay timer to
reduce power dissipation during a continuous load fault
-- Cycle-by-cycle over-current limiting to protect power supply components
from instantaneous overload conditions
-- Unique, current-mode opto-coupler interface that increases the
bandwidth of conventional opto-couplers
-- Precision 5V output that eliminates the need for an external reference
or a bias supply for housekeeping circuits
