Controller integrates more for efficient
design
A 100V half-bridge pulsewidth modulation controller offers the industry's highest level of integration to minimise the overall solution size of half-bridge DC/DC convertors.
National Semiconductor has introduced a 100V half-bridge pulsewidth modulation (PWM) controller that offers the industry's highest level of integration to minimise the overall solution size of half-bridge DC/DC convertors National will be demonstrating the LM5035 at PCIM Europe (30th May to 1st June 2006, Nuremberg, Germany) in Hall 12, Booth 124

National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
The LM5035, the newest member of National's high-voltage LM5000 family, integrates a voltage-mode PWM controller with high-side and low-side 2A peak gate drivers plus two programmable, secondary-side synchronous rectifier FET drivers.
Programmable control of the rectifying switches allows designers to perfect their timing relationship to optimise overall power efficiency.
Applications for LM5035 half-bridge power supplies include telecommunications, data communications and industrial control systems where power density and efficiency are primary concerns.
"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.
"With the LM5035, National has integrated core IP from our LM5100A gate driver and LM5025 PWM controller on a single chip".
"The result is a robust solution with industry-leading power density for highly compact power modules such as one-eighth and one-sixteenth bricks".
The LM5035 half-bridge controller and gate driver contains all of the features necessary to implement half-bridge-topology power convertors using voltage-mode control with line feed-forward.
Available now, the LM5035 is priced at $1.90 in 1000-unit quantities.
