Analog Devices / Maxim Integrated MAX17501/02/03 Step-Down DC-DC Converters

Analog Devices MAX17501/MAX17502/MAX17503 Step-Down DC-DC Converters with integrated MOSFETs operate over a 4.5V to 60V input voltage range. These Maxim Integrated devices feature peak-current-mode control with pulse-width modulation (PWM). The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout. A programmable soft-start feature allows users to reduce input inrush current. These step-down DC-DC converters also incorporate an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input voltage level.

Features

  • No Schottky-synchronous operation for high efficiency and reduced cost
  • Internal compensation and feedback divider for 3.3V and 5V outputs
  • All-ceramic capacitors, ultra-compact layout
  • Wide 4.5V to 60V input voltage range
  • 0.9V to 92% VIN output voltage
  • Delivers up to 500mA (MAX17501), 1A (MAX17502), or 2.5A (MAX17503)
  • 600kHz and 300kHz switching frequency options
  • Reduces power dissipation
  • Peak efficiency >90%
  • PFM for high light-load efficiency (MAX17501)

Applications

  • Industrial process control
