深圳市泰德兰电子有限公司-***一级代理日本TOREX|台湾Axelite产品。
- The XC9244/XC9245 series is a group of synchronous-rectification type step-down DC/DC converters with a built-in 0.65Ω P-channel MOS driver transistor and 0.45Ω N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. Output current of 400mA (MAX.) to be configured using only a coil and capacitor connected externally.
- The output voltage can be set from 0.8V to 4.0V in increments of 0.05V (accuracy: &plu***n;2.0%). With an internal switching frequency of 1.2MHz, ***all external components can be used. USPN-6 package is suitable for the application which requires low profile and ***all-footprint.
特点:
- Driver Transistor Built-In :0.65Ω P-ch Driver Transistor,0.45Ω N-ch Driver Transistor
- Input Voltage: 2.3V ~ 6.0V
- Output Voltage Selectable :0.8V ~ 4.0V (0.05V Increments)
- High Efficiency :90% (TYP.) ,* The characteristics change with external parts, substrate wiring, etc.
- Output Current: 400mA
- Oscillation Frequency :1.2MHz (&plu***n;15%)
- Maximum Duty Cycle:100%
- Function: Current Limiter Circuit(C***tant Current & Latching),CL High Speed Discharge ,Soft Start Circuit
- Capacitor: Low ESR Ceramic Capacitor
- Control Methods: PWM (XC9244),PWM/PFM Auto (XC9245)
- Operating Ambient Temperature :-40℃~+85℃
- Package :USPN-6
- XC9246/XC9247系列产品是内置驱动晶体管、工作于16V的***DC/DC转换器IC,实现了输出电流为1.0A的***率稳定电源。此外,陶瓷电容等低ESR电容作为负载电容CL使用。
- 内置了1.0V的基准电压源、可以用外置电阻设定任意的输出电压。因为开关频率为1.2MHZ的高频,有利于外置零部件的小型化。虽然在内部把软启动时间设定为1ms(TYP),但也可以通过连接于EN/SS引脚的电容任意的设定。
- 可以从PWM控制(XC9246)、或PWM/PFM自动转换控制(XC9247)中选择工作模式。实现了从轻负载到重负载的整个负载范围内的高速响应、低纹波、***率。
- 内置了输入欠压锁闭功能,当低于检测电压时强制停止驱动晶体管工作。内置了过流保护电路、过热停机电路、短路保护电路。能保证安全地使用有SOT-26W、USP-6C两种封装可供选择。
特点:
- 输入电压范围:4.5V或7V--16V(******大额定值:22V)
- 输出电压:1.0V&plu***n;15%的基本电压源
- 输出电流:Vin ≧6V且Vout/Vin≦0.5 1A
- Vin <6V且Vout/Vin≦0.4 1A
- ***率:90%
- 工作频率:1.2MHZ
- ***大占空比:80%
- 软启动:内部设定为1ms
- 工作模式:PWM固定控制 XC9246
- PWM/PFM自动切换 XC9247
- 工作温度范围:-40°C--+85°C
