CXSD6155 Cxsd6155a is a high efficiency, 1.2MHz fixed working frequency, current mode PWM single-chip voltage regulator, which is very suitable for the portable products powered by a single lithium-ion battery, when the peak working current can reach 2a, the efficiency still needs to reach more than 90%. The duty cycle of cxsd6155 cxsd6155a can reach 100% in the low-voltage differential operation mode, which extends the battery life of portable devices. When the output load becomes low, cxsd6155 cxsd6155a works in pulse hopping mode, which ensures low output ripple voltage and is conducive to noise sensitive application environment. The input working voltage range is 2.5V to 6.0V, the output current can reach 2a, and the output voltage can be as low as 0.6V. The switching frequency of 1.2MHz enables the peripheral components to be miniaturized, and the internal compensation design enables the use of small inductance (which can reduce the volume) to maintain high efficiency. Cxsd6155 cxsd6155a has two packaging forms of 3mmx3mm10 pin dfnwb and MSOP, and the operating temperature range is - 40 ℃ ~ + 85 ℃
