ROHM的二次LDO稳压器系列能够使正在追求小型化、节能化的各种装置限度地发挥其性能,构成低噪声而又稳定工作的电源电路。用于局部电源的500mA可变输出二次LDO稳压器系列,是可以利用外接电阻器将输出电压设定为1.0V~4V的可变输出低饱和型稳压器,其输出电压精度为±1%,可提供500mA的输出电流。能广泛应用于TV、HDD、PC、DVD等等。本系列产品内置有防止输出短路等原因损毁IC的过流保护电路、防止过负荷状态等产生的热破坏IC的温度保护电路。
dzsc/19/2947/19294795.jpgBD8381EFV-M is a white LED driver with the capability of withstanding high input voltage (50V Max.). A current-mode buck-boost DC/DC controller is also integrated to achieve stable operation against voltage input and also to remove the constraint of the number of LEDs in series connection. The brightness can be controlled by either PWM or DC. The PWM brightness signal generation circuit is built into, and the control without microcomputer is also possible.
