AX3037-200KHz,Synchronous PWM Buck Controller DataSheet (2015年7月停产)
GENERAL DESCRIPTION The AX3037 series are monolithic IC designed for a synchronous step-down DC/DC controller. The AX3037 together with dual N-channel MOSFETs and provide a low cost solution for applications. This device features an internal 200KHz oscillator, under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under- voltage detection that latches off the device when an output short is detected. The chip is available in SOP-8L and SOP8-EP packages.
FEATURES - Output voltage: adjustable output version - Operating with single 5V or 12V supply voltage - Fixed switching frequency is 200KHz - Soft-start time for outside programmed - SOT23-5L and SOP-8L packages - 500mA Peak Output Drive Capability - Under Voltage Luck-Out for Vc and Vcc input - Output Protection When control FET is shorted - SOP-8L and SOP8 with Exposed Pad Pb-Free packages. |
