TPS54340/60 Step-Down Converter with Eco-mode

42/60 V, 3.5 A, step-down regulator with an integrated high-side MOSFET

Image of Texas Instruments' TPS54360 Step-Down Converter with Eco-modeTexas Instruments' TPS54340/60 is a 42/60 V, 3.5 A, step-down regulator with an integrated high-side MOSFET. The device survives load dump pulses up to 45/65 V per ISO 7637. Current-mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load supply current to 146 µA. Shutdown supply current is reduced to 2 µA when the enable pin is pulled low.

Undervoltage lockout is internally set at 4.3 V but can be increased using the enable pin. The output voltage start up ramp is internally controlled to provide a controlled start up and eliminate overshoot.

Features
  • 4.5 V to 42/60 V (45/65 V Abs max) input range
  • 3.5 A continuous current, 4.5 A minimum peak inductor current limit
  • Current mode control DC-DC converter
  • 92 mΩ high-side MOSFET
  • High efficiency at light loads with pulse skipping Eco-mode

Applications

  • 12 V, 24 V and 48 V industrial, automotive, and communications power systems
