• STEVAL-ISV006V2: solar battery charger using the SPV1040 AN3319

STEVAL-ISV006V2 has been designed to recharge any type of battery (except lithium

compound) which maximum voltage (VBATT_max) ≤ 5.2 V and supplied by up to 5 W PV

panels (constrained by VOC<VBATT_max).

• Buy at digikey price $5

• 0.3 V to 5.5 V operating input voltage

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
• 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.
