For a 1.2 A load at 1.5 V, the input current at 3.3 V nominal is about 0.6 A, so the upstream supply rail needs to budget for that plus the converter's quiescent draw. ## Package and thermal: 10-MSOP with exposed pad The 1.25 MHz switching frequency means the inductor and output capacitor can be small, but the input decoupling cap should be placed close to the VIN pin to minimise input ripple.","metaTitle":"TPS62042DGQG4 Buck Converter, 1.2 A, 1.25 MHz, Active","metaDescription":"Texas Instruments TPS62042DGQG4 step-down buck converter, 1.2 A output, 1.25 MHz switching, -40°C to 85°C, 10-MSOP.
