Terex launched 400nA PWM/PFM ultra-low consumption current boost DC/DC converter

     Terex Semiconductor Co., Ltd. has developed the 400nA PWM/PFM ultra-low consumption current boost DC/DC converter XC9145 series. With the ultra small package WLP-6-05 (1.08 x 1.28 x 0.4 mm), an ultra small real installed area of 5.4 x 6.7 mm can be achieved even if small coils and ceramic capacitors are installed externally (Figure 3). High standby efficiency can reduce the size and capacity of the battery, which is conducive to the miniaturization of the entire equipment.

     XC9145 series ultra-low current consumption circuit reduces the current consumption to 400nA. At the same time, PWM/PFM control mode is used to significantly improve the efficiency of the product under light load, especially when the output current is small μ A, the efficiency is greatly improved compared with the traditional DC/DC converter. VIN=2.4V、VOUT=3.3V、IOUT=10 μ The efficiency of A is 89.9%, compatible with low power consumption MCU and SoC. Without complex control, it can also significantly reduce the power consumption of IoT and portable devices with large system standby time under constant boost operation, contributing to extending the battery life

     In addition, the working environment temperature of XC9145 series can reach+105 ° C, which is applicable to IoT/mobile/wearable devices requiring long battery life, as well as industrial devices requiring small size, light load and high efficiency.
