Beschreibung

The MCP19035 is a highly-featured, highly-integrated, Synchronous Buck Controller in a space-saving 10-pin DFN 3 x 3 mm package, that operates from input voltage sources up to 30V. Integrated features include high and low-side MOSFET drivers, fixed-frequency voltage mode control, internal oscillator and reference voltage generator, overcurrent protection on both the high- and low-side devices, Power Good circuit and overtemperature protection. A minimal number of external components are necessary to develop a complete, high-performance Synchronous Buck Converter power supply.

Eigenschaften

  • Input Voltage Range: 8V to 14V
  • Output Voltage: 1.8V (can be adjusted by changing one resistor between 0.9V and 3.3V)
  • Maximum Output Current: 15A
  • 91% typical efficiency at 1.8V/15A output and 12V input
  • 300 kHz fixed switching frequency
  • On-board High Performance Power MOSFET Transistors
  • Overcurrent Protection for High and Low-Side MOSFETs
  • Power Good (PGOOD) output for monitoring the output voltage quality
  • Shutdown input for placing the converter in a low-power Standby mode
  • Under Voltage Lockout (UVLO) with 4.5V and 3.9V (typical) thresholds

Typische Anwendungen

  • Medium current Point-of-Load converters, Industrial 24V rails converters, FPGA/DSP power supplies
  • Digital Set-Top boxes
