TLV61070A device is a synchronous boost converter with 0.5V ultra-low input voltage. The device provides a power supply design for portable equipment and smart devices powered by various batteries and super capacitors. The TLV61070A has typical 2.5A valley switch current limit over full temperature range. With a wide input voltage range of 0.5V to 5.5V, the TLV61070A supports super capacitor backup power applications, which can deeply discharge the super capacitor.

The TLV61070A operates at 1MHz switching frequency when the input voltage is above 1.5V. The switching frequency decreases gradually to 0.55MHz when the input voltage is below 1.5V down to 1V. The TLV61070A enters power-save mode at light load condition to maintain high efficiency over the entire load current range. The TLV61070A consumes a 20µA quiescent current from VOUT in light load condition. During shutdown, the TLV61070A is completely disconnected from the input power and only consumes a 0.1µA current to achieve long battery life. The TLV61070A has 5.7V output overvoltage protection, output short circuit protection, and thermal shutdown protection.

The TLV61070A offers a very small design size with 2.9mm × 2.8mm SOT23-6 package and minimum amount of external components.
