Switching Regulator ICs offer 4 levels of protection.

Press Release Summary:



Manufactured in DIP-8 package, STR-A6251/51M/52 series is comprised of off-line PWM topology SMPS primary switchers with jittering function for reduction of EMI noise-filtering circuits. They offer frequency jittering for SMPS up to 20 W universal input, and external adjustment capability enables optimal jitter-frequency setting. Along with primary controlled CV/CC operation, auto-standby, and soft-start functions, products incorporate avalanche-energy-guaranteed MOSFET.

Allegro Introduces Low-Power Off-Line SMPS Primary Switchers



Sanken's ICs offer frequency jittering for SMPS up to 20 W universal input

Worcester, MA - Aug. 24, 2005 - Allegro continues to expand its power management family with the STR-A6251/51M/52 from Sanken Electric Company, Ltd. Allegro is a wholly owned subsidiary of Sanken Electric Company, Ltd., a $1.4 billion company that manufactures semiconductors, discretes, LEDs, and switch-mode power supplies, with headquarters in Saitama, Japan. The two companies jointly develop and market leading-edge products in the areas of power management and motion control.

The series STR-A6200 is comprised of relatively low-output power off-line PWM topology switching regulator ICs that have a jittering function for cost reduction of EMI noise-filtering circuits. An external adjustment capability provides an optimum jitter-frequency setting. Each device includes various critical and useful functions to realize a simple and reliable design in a switched-mode power supply system, such as primary controlled CV/CC operation, auto-standby, soft-start, protections (overload, overcurrent, overvoltage and thermal), and an avalanche-energy-guaranteed MOSFET.

Targeted at the consumer, communication, industrial and home appliance markets, the series STR-A6200 is provided in a DIP-8 package and has a 12-week ARO leadtime. Pricing is $1.09 for quantities of 1,000.

Allegro MicroSystems, Inc. is a supplier of advanced mixed-signal power semiconductors and Hall-effect sensors targeted toward the automotive, communications, computer/office automation, consumer and industrial markets. It maintains a leadership position in the integrated magnetic sensor and integrated motor driver product segments. With more than 2,000 employees, Allegro is headquartered in Worcester, MA.
