TPS54260DGQR

TPS54260DGQR is a 2.5 A step-down converter with a 3.5 V to 60 V input range in an MSOP-10 PowerPAD (DGQ) package, integrating a 200 mOhm high-side MOSFET. The switching frequency adjusts from 100 kHz to 2.5 MHz, Eco-mode operation keeps light-load efficiency high, quiescent current is 138 µA, and the junction temperature rating reaches +150 C. For 24 V and 48 V industrial rails, vehicle accessory power and telecom line cards, the 60 V input tolerance absorbs load-dump and inductive transients that would destroy lower-voltage converters, so one design can serve harsher rails without extra clamping parts. Selection advice: size the inductor and switching frequency for your worst-case input voltage, because duty-cycle limits bite at high step-down ratios; if the output current must exceed 2.5 A continuously, step up to a higher-current converter rather than relying on thermal margins.
