Product Details

The ADP5014 combines four high performance, low noise buck regulators in a 40-lead LFCSP package. Relying on its low output noise (~25 μV rms when VOUT ≤ VREF), the low noise buck regulator enables the powering up of the noise sensitive signal chain products.

All channels in the ADP5014 integrate high-side and low-side power metal-oxide semiconductor field effect transistors (MOSFET). Channel 1 and Channel 2 deliver a programmable output current of 2 A or 4 A. Combining Channel 1 and Channel 2 in a parallel configuration provides a single output with up to 8 A of current.

Channel 3 and Channel 4 deliver a programmable output current of 1 A or 2 A. Combining Channel 3 and Channel 4 in a parallel configuration can provide a single output with up to 4 A of current.

The ADP5014 features two enable modes. The manual mode has four individual precision enable pins to enable each regulator manually. Alternatively, the sequence mode has one grouped precision enable signal with programmable power-up and power-down delay timers on each rail for specific rail sequence requirements.

The switching frequency of the ADP5014 can be programmed or synchronized to an external clock from 500 kHz to 2.5 MHz.

The ADP5014 offers other key features like selective forced pulse width modulation (FPWM)/power saving mode (PSM), an undervoltage output (UVO), active output discharge, and a power-good flag. Other safety features include input undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP) and thermal shutdown (TSD).

Applications

  • RF transceiver, high speed analog-to-digital converter (ADC)/digital-to-analog converter (DAC), mixed signal ASIC
  • FPGA and processor applications
  • Security and surveillance
  • Medical applications
