Description

The TPS54610 low-input voltage high-output current synchronous buck PWM converter integrates all required active components. Included on the substrate with the listed features are a true, high performance, voltage error amplifier that enables maximum performance and flexibility in choosing the output filter L and C components; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally or externally set slow-start circuit to limit inrush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing.

The TPS54610 is available in a thermally enhanced 28-pin HTSSOP (PWP) PowerPAD™ package, which eliminates bulky heatsinks. TI provides evaluation modules to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.

Features

  • 30-mΩ, 12-A Peak MOSFET Switches for High Efficiency at 6-A Continuous Output Source or Sink Current
