目录7.相关产品 产品概述 返回TOP The CXSU63134 is a single PWM, step-up DC-DC controller with low operating voltage application integrating softstart and short circuit detection function. The oscillator switching frequency on chip can be operated by terminating OSC pin to connect capacitor and resistor for adjustable operating frequency. Soft-start is adjusted with the external capacitor, which sets the input current ramp. Besides, the external compensation FB pin will apply the flexibility in the dynamic loop status, which allows using small and low equivalent series resistance (ESR) ceramic output capacitors产品特点 返回TOP · 2.5 to 5.5V Input Voltage Range · Adjustable Frequency: Maximum 1MHZ · Incorporates Soft-Start Function · Built-in Short-Circuit Detection Circuit (SCP) · Low Operating Current: Maximum to 1mA · Low Shutdown Current: Maximum to 1mA · Package: SOP-8, MSOP-8, TDFN2x2-8 and TSSOP-8 · Under-Voltage Lockout · Lead Free and Green Devices Available (RoHS Compliant) 应用范围 返回TOP · LCD Display Power Source · Camcorders VCRs, MP3, and Digital Still Camera · Hand-held and Communication Instruments · PDAs 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 产品封装图 返回TOP
