1 / 15 page  October 2011 Doc ID 18080 Rev 3 1/15 15 SPV1040 High efficiency solar battery charger with embedded MPPT Features ■ 0.3 V to 5.5 V operating input voltage ■ 140 mΩ internal synchronous rectifier ■ 120 mΩ internal power active switch ■ 100 kHz fixed PWM frequency ■ Duty cycle controlled by MPPT algorithm ■ Output voltage regulation, overcurrent and overtemperature protection ■ Input source reverse polarity protection ■ Built-in soft-start ■ Up to 95% efficiency ■ 3 mm x 4.4 mm TSSOP8 package Applications ■ Smart phones and GPS systems ■ Wireless headsets ■ Small appliances, sensors ■ Portable media players ■ Digital still cameras ■ Toys and portable healthcare Description The SPV1040 device is a low power, low voltage, monolithic step-up converter with an input voltage range from 0.3 V to 5.5 V, and is capable of maximizing the energy generated by even a single solar cell (or fuel cell), where low input voltage handling capability is extremely important. Thanks to the embedded MPPT algorithm, even under varying environmental conditions (such as irradiation, dirt, temperature) the SPV1040 offers maximum efficiency in terms of power harvested from the cells and transferred to the output. The device employs an input voltage regulation loop, which fixes the charging battery voltage via a resistor divider. The maximum output current is set with a current sense resistor according to charging current requirements. The SPV1040 protects itself and other application devices by stopping the PWM switching if either the maximum current threshold (up to 1.8 A) is reached or the maximum temperature limit (up to 155 °C) is exceeded. An additional built-in feature of the SPV1040 is the input source reverse polarity protection, which prevents damage in case of reverse connection of the solar panel at the input. Table 1.
