Productoverzicht

The TPS54061DRBT is a 60V/200mA synchronous Step-down DC-DC Converter with integrated high-side and low-side MOSFETs. Current mode control provides simple external compensation and flexible component selection. The non-switching supply current is 90 µA. Using the enable pin, shutdown supply current is reduced to 1.4µA. To increase light load efficiency the low-side MOSFET emulates a diode when the inductor current reaches zero. Under-voltage lockout is internally set at 4.5V, but can be increased using two resistors on the enable pin. The output voltage start-up ramp is controlled by the internal slow-start time.
  • Integrated high-side and low-side MOSFET
  • Diode emulation for improved light load efficiency
  • Peak current mode control
  • 90µA Operating quiescent current
  • 1.4µA Shutdown current
  • 50 to 1100kHz Adjustable switching frequency
  • Synchronizes to external clock
  • Internal slow-start
  • 0.8V ±1% Voltage reference
  • Stable with ceramic output capacitors or low-cost aluminium electrolytic
  • Cycle-by-cycle current limit, thermal, OVP and frequency foldback protection
  • Green product and no Sb/Br
