Product Description

The TPS61021ADSGR Electronic Components synchronous step-up converter is designed to operate from an input voltage supply range between 0.5 V and 4.4 V with 3-A valley switch current limit. The TPS61021ADSGR typically operates at a quasiconstant frequency pulse width modulation (PWM) at moderate to heavy load currents. The switching frequency is 2 MHz when the input voltage is above 1.5 V.

The switching frequency reduces down to 1 MHz when the input voltage goes down from 1.5 V to 1 V. At light load currents, the TPS61021A converter operates in power-save mode with pulse frequency modulation (PFM). During PWM operation, the converter uses adaptive constant ontime valley current mode control scheme to achieve excellent line/load regulation and allows the use of a small inductor and ceramic capacitors. Internal loop compensation simplifies the design process while minimizing the number of external components.

Product Features

The TPS61021ADSGR provides a power supply solution for portable or smart devices powered by alkaline, NiMH, Li-Mn, or Li-ion batteries. The TPS61021ADSGR is capable of outputting 3.3-V voltage and 1.5-A current from a battery discharged to as low as 1.8 V. Capable of operating with 0.5-V input voltage enables the TPS61021ADSGR to extend the battery run time.
