Guangdong introduced a new core source input voltage 25VDC-60VDC high voltage step-down DC / DC chip, the power down chip adjustable oscillator frequency 52KHZ to work in the best condition. An on-chip reference power supply, oscillator, error amplifier, an external without an external start-up resistor. The chip integration, the chip has a higher stability. The chip uses a standard ESOP8 two lead-free package, is now available in large quantities. Chip Applications: Electric bicycles electric motorcycle instrument control system instrumentation control system voltage analog / digital system industrial control systems telecommunications power supply systems Ethernet POE systems Main products: lithium charge management IC double single 8.4V lithium rechargeable lithium tweezers cadmium batteries mouse boost ultra-low power IC DC-DC regulator IC car charger car charger IC program Car LED lighting driver IC output constant voltage car charger with a line of complementary high voltage 60V car charger IC regulator IC lithium battery Charge Management IC 3.7V 5V liter high current boost IC LED Driver IC charger IC boost IC urgent boost charge current boost regulator IC LED lamp driver IC electric toys IC high efficiency boost DC-DC step-down IC Wide Input high current incandescent lamp driver IC LED flashlight IC synchronous rectification IC boost synchronous buck IC DC / DC step-down IC solar lawn IC output adjustable low-voltage detection IC buck IC touch IC 8 key touch IC 6 key touch IC double touch Speed ??Touch IC IC chip 24-key touch-key touch IC 36 key touch IC three-terminal regulator IC LDO LDO 22V power supply 40V buck buck LDO widely core source of Jiang Nan phone: 134 2429 7678 QQ: 1004509729 E-mail: mk008@zgsemi.com Luo phone: 134 2514 6336 QQ: 2805981750 E-mail: mk003@zgsemi.com Leung Mobile: 183 1938 1531 QQ: 2671598306 E-mail: mk99@zgsemi.com Willow phone: 136 3252 9254 QQ: 2466385476 E-mail: mk015@zgsemi.com Liu Mobile: 150 1404 3136 QQ: 1748986374 E-mail: mk006@zgsemi.com business phone: 138 2657 2159 QQ: 2573705058 E-mail: mk999@zgsemi.com Phone: 0755-29469758 company's Web site: http://www.086ic.cn Corporate Website: http: //www.zgsemi.com http://www.nxppower.com
