Allegro MicroSystems Intros STR-A6200 Series Devices
Allegro MicroSystems Inc. (Worcester, MA), a supplier of mixed-signal power semiconductors and hall-effect sensors, has expanded its power management family with the STR-A6251/51M/52 from Sanken Electric Company Ltd. (Saitama, Japan), which manufactures semiconductors, discretes, LEDs, and switch-mode power supplies. Allegro is a wholly owned subsidiary of Sanken Electric, and the the two companies jointly develop and market power management and motion control products.
The STR-A6200 Series is comprised of low-output power, off-line, pulse-width-modulation topology, switching regulator ICs that have a jittering function for cost reduction of EMI noise-filtering circuits. An external adjustment capability provides a 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, over-current, over-voltage, and thermal), and an avalanche-energy-guaranteed MOSFET.
Targeted at the consumer, communication, industrial, and home appliance markets, the STR-A6200 Series is provided in a DIP-8 package, and has a 12-week ARO lead time. Pricing is $1.09 for quantities of 1,000.
