The MAX17682 is a high-voltage, high-efficiency, iso-buck DC-DC converter designed to provide isolated power up to 10W. The device operates over a wide 4.5V to 42V input voltage range and uses primary-side feedback to regulate the output voltage. It delivers primary peak current up to 3.7A and regulates primary output voltage to within ±1.2% over -40°C to +125°C.

The device features peak-current-mode control with pulse-width modulation (PWM) scheme. 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. The device also incorporates an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired inputvoltage level. An open-drain, active-low RESETB pin provides a delayed power-good signal to the system upon achieving successful regulation of the primary output voltage.

The device operates over the -40°C to +125°C industrial temperature range and is available in a compact 20-pin (4mm x 4mm) TQFN package. Simulation models are available.

Applications

  • Communication Hub in Smart Meters
  • Floating Power Supply Generation
  • Industrial Process Control
  • Isolated Power Supplies in Medical Equipment
