Product Overview

The MAX17498BATE+T from Maxim Integrated Products is an AC to DC and DC to DC peak current-mode converter for flyback/boost applications in 16 pin TQFN package. The current-mode fixed-frequency flyback/boost converter. The MAX17498B support UVLO thresholds suitable to low voltage DC to DC applications. An EN/UVLO input allows the user to start the power supply precisely at the desired input voltage while also functioning as an on/off pin. The OVI pin enables implementation of an input overvoltage-protection scheme that ensures that the converter shuts down when the DC input voltage exceeds the desired maximum value. The device incorporates a flexible error amplifier and an accurate reference voltage to enable the end user to regulate both positive and negative outputs. Programmable current limit allows proper sizing and protection of the primary switching FET.
  • Supply voltage range is 4.5V to 36V
  • Operating temperature range from -40°C to +125°C
  • Fixed switching frequency is 500KHz
  • Flexible error amplifier to regulate both positive and negative outputs
  • Programmable soft-start to reduce input inrush current
  • Programmable voltage or current soft-start
  • Hiccup mode overcurrent protection and thermal shutdown
  • Minimize dissipation under overcurrent and overtemperature fault conditions
  • Low RDSON, 175mohm, 65V rated internal n-channel MOSFET
  • Optional spread spectrum, maximum duty cycle greater than 92%
  • Front-End AC/DC Power Supplies for Industrial Applications (Isolated and Nonisolated);
  • Telecom Power Supplies; Wide Input Range DC Input Flyback/Boost Industrial Power Supplies
