The SY87004A is a high efficiency, synchronous boost converter with bypass mode. The device is designed to operate in bypass mode by providing a low resistance path between the output and input when the input voltage is higher than the target voltage. It transition automatically into boost mode when the input voltage is lower than the desired output. The SY87004A operates over a wide input voltage range from 1.9V to 5.5V and supports up to 6A maximum load current in bypass mode. Overtemperature, overcurrent, as well as output undervoltage and input overvoltage protections are provided reliable operation. The device operation and parameters can be configured using the I2C bus.
