AX3037-200KHz,Synchronous PWM Buck Controller停产


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.
