General Description

AX1010 is a power management chip developed by BCD process with laser driving function at transmitter end. This chip has two application modes of low power and high power, and wide range of input and output voltage. With multiple output function, it can drive one laser and three sensors simultaneously. AX1010 has built-in over-current protection and over-temperature protection, and the output voltage can be multi-gear adjusted through register according to the needs. At the same time, AX1010 has the function of saving power automatically under light load, which can ensure that it has higher efficiency in a large load range. AX1010 has the advantage of high integration, which can greatly reduce the system cost and power consumption.

Product Features:

●   With automatic power saving mode

●   Wide range of output voltage

●   Multi-channel output with high-efficiency

●   Built-in over-current and over-temperature protection functions

●   Multi-gear adjustment voltage
