In the Lighting technical session, which is dedicated to new control
methods, circuit topologies, control ICs, and power management solutions, ST
will introduce an IC that simplifies lighting ballast design by integrating in
a single chip the Power Factor Corrector and half-bridge controllers and all
the relevant drivers, protections and features to generate more light from less
energy, while ensuring full compliance with safety and power consumption
regulations.
A special session at PSW 2006 is dedicated to design techniques and new
technologies able to satisfy the increasingly demanding requests of high
performance and efficiency in portable devices. Addressing this topic, ST will
look at how to efficiently power the operation of Double Data Rate 2 and Double
Data Rate 3 memories in portable applications, such as notebooks and Personal
Digital Assistant (PDA) systems.
ST will also present two important papers that deal specifically with motor
speed control in various applications. In particular, one paper introduces a
new, all digital, complete dual H-bridge driver integrated circuit for use in
small motor-drive applications such as stepper and Direct-Current (DC) motors.
Another paper focuses on a simple, linear, cost-effective torque control method
for use with Brushless DC (BLDC) motors, which are commonly found in blowers,
domestic appliances, electric tools, and devicesrequiring good speed
control.
In an invited session, ST will report on the ESBT® (Emitter-Switched Bipolar
Transistors) technology as an ideal solution providing advantages in both
performance and cost when using converters with a flyback topology. The flyback
converters, operating in quasi-resonant (QR) mode, are one of the most popular
and simplest ways to increase the efficiency of applications, such as notebook
adapters, printers, or Switched-Mode Power Supply (SMPS) for TVs.
New processors for desktop PCs, servers, and telecom and communication
systems demand higher current levels while requiring compliance with a tighter
voltage regulation. ST engineers will illustrate, in two papers, how to improve
the overall system performance by applying the Load Transient Boost Technology
TM (LTB TechnologyTM) to multi-phase DC-DC converters or
by optimizing the MOSFET parameters separately for the high side and low side
switch.
