SSP8018
SSP8018 is a synchronous boost converter designed for battery-powered devices. The device supports a variety of battery types, including alkaline, nickel-metal hydride rechargeable batteries, lithium-manganese batteries, and lithium-ion rechargeable batteries. Its standout advantage lies in its high efficiency under light load conditions, a characteristic crucial for extending battery life.
In the application scenario of 3.3V boost to 5V, the chip is able to output current up to 300mA. Of particular note is the system achieving up to 90% conversion efficiency at a load current of 200mA.
SSP8018 chip offers two operating modes to suit different application scenarios: buck mode and pass-through mode. In buck mode, when the input voltage is higher than the output voltage (VOUT<VIN<VOUT + 0.3V), the chip can still accurately adjust the output voltage to the target value.
This mode is suitable for scenarios where a stable output voltage is required. When the input voltage exceeds the output voltage by more than 0.3V (VIN>VOUT + 0.3V), the chip automatically switches from buck mode to pass-through mode. In pass-through mode, the output voltage will follow the input voltage.
SSP8018 has a true shutdown function that completely disconnects the load from the input power supply when the device is disabled, significantly reducing current consumption.
SSP8018 is available in a fixed output voltage version.
