Product Overview
The TPS82140 is a Texas Instruments step-down converter module for Power_Management designs requiring a compact integrated power stage. It is supplied in an 8-pin µSiL (SIL0008C) package with 3.0 mm x 2.8 mm x 1.5 mm dimensions and includes an integrated 1 µH inductor. Recommended operating conditions specify a 3.0 to 17 V input range, 0 to 2 A output current, and adjustable 0.9 to 6 V output voltage.
The module uses DCS-Control topology for PWM and Power Save Mode operation, with a typical PWM switching frequency of 2.0 MHz at 1 A and 1.8 V output. It supports 100% duty-cycle operation for low dropout conditions, programmable soft startup with tracking through the SS/TR pin, and an open-drain PG output with pull-up voltage below 6 V. Thermal data includes 58.2 °C/W junction-to-ambient resistance under JEDEC 51-5 and 46.1 °C/W on the EVM.
