The TPS54010 low-input voltage, high-output current synchronous buck PWM converter in a dc/dc regulator integrating all required active components. Included on the substrate with the listed features are a true, high- performance, voltage error amplifier that enables maximum performance under transient conditions and flexibility in choosing the output filter L and C components; an undervoltage-lockout circuit to prevent start-up until the VIN input voltage reaches 3 V; an internally and externally set slowstart circuit to limit in-rush currents; and a power-good output useful for processor/logic reset, fault signaling, and supply sequencing.

The TPS54010 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heat sinks.

TPS54010EVM-067 — 14 A, 2,2–4,0 Vin, Evaluierungsmodul für DC/DC-Wandler mit einstellbarer Ausgangsspannung

The TPS54010EVM-067 kit allows the designer to evaluate the 14-A TPS54010 synchronous buck DC/DC converter with integrated power MOSFETs. The input voltage range is 3.0 V to 3.6 V and the power stage input is 2.2 V to 4.0 V. The output voltage is adjustable down to 0.9 V (module preset to 1.5 V). (...)
