Product Overview
The TPS62080 is a Texas Instruments synchronous step-down converter for Power_Management rails requiring conversion from a 2.3 to 6 V input range. The TPS62080 and TPS62080A adjustable versions support an output voltage range from 0.5 to 4.0 V, with a 0.45 V typical feedback regulation voltage and 10 nA typical feedback input bias current at VFB = 0.45 V.
The device family supports a maximum output current of 1.2 A and 100% duty-cycle operation for lowest-dropout operation. Electrical characteristics include 30 µA typical quiescent current when not switching, 6.5 µA typical quiescent current in snooze mode, 95 mΩ typical high-side FET on-resistance, and 70 mΩ typical low-side FET on-resistance.
The TPS62080 is supplied in an 8-pin WSON (DSG) package with a 2.00 mm x 2.00 mm body and thermal pad. Thermal data for the DSG package includes 59.7 °C/W junction-to-ambient resistance and 8.6 °C/W junction-to-case bottom resistance. Protection and monitoring parameters include undervoltage lockout, power-good thresholding, output discharge resistance, thermal shutdown, and defined EN/MODE logic thresholds.
