The SPV1040 is a high-efficiency solar battery charger with embedded MPPT. It is suitable for applications such as smart phones, GPS systems, wireless headsets, small appliances, sensors, portable media players, digital still cameras, toys, and portable healthcare devices. The product features a 0.3V to 5.5V operating input voltage range, 140mΩ internal synchronous rectifier, 120mΩ internal power active switch, 100kHz 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, and up to 95% efficiency.
The SPV1040 is a low power, low voltage monolithic step-up converter designed to maximize energy harvested from a single solar cell or fuel cell. It features an embedded Maximum Power Point Tracking (MPPT) algorithm that adjusts the duty cycle to maintain maximum efficiency under varying environmental conditions such as irradiation, dirt, and temperature changes. The device is capable of operating with input voltages ranging from 0.3 V to 5.5 V.
