TitleSwitching Voltage Regulators DC-DC Converter 4.5V to 42V Input
Description

Maxim MAX17682 Iso-Buck DC-DC Converter 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. This device delivers primary peak current up to 3.7A and regulates the primary output voltage to within 1.2% over -40C to +125C. The MAX17682 features peak-current-mode control with pulse-width modulation (PWM) scheme. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplifies the layout. A programmable soft-start feature allows users to reduce input inrush current. The device also incorporates an output enable/under voltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input voltage 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.

Features, Applications

to 42V Input, Ultra-Small, High-Efficiency, Iso-Buck DC-DC Converter

The is a high-voltage, high-efficiency, iso-buck DC-DC converter designed to provide isolated power to 10W. The device operates over a wide to 42V input voltage range and uses primary-side feedback to regulate the output voltage. It delivers primary peak current to 3.7A and regulates primary output voltage to within 1.2% over to +125C. 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 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 to +125C industrial temperature range and is available in a compact x 4mm) TQFN package. Simulation models are available.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Junction temperature greater than +125C degrades operating lifetimes.
