Overview

TopologyBuck Converter
Input voltage8-135 V
Output 15.5 A

Description

Demonstration circuit 2537A is a 135V protected, high side switch featuring the LT C®7000. The demo board is designed to switch a 5.5A output load from input voltages from 8V to 135V. The wide input range and low shut-down current (1μA typical) make it suitable for automo-tive, industrial, medical instrument and telecom applica-tions. This board offers a low 50ns (typical) propagation delay, fast switching times (<10ns) and 100% duty cycle operation.

Features

  • Wide Operating VIN: 3.5V to 135V (150V Abs Max)
  • 1Ω Pull-Down, 2.2Ω Pull-Up for Fast Turn-On and Turn-Off Times with 35ns Propagation Delays
  • Internal Charge Pump for 100% Duty Cycle
  • Short-Circuit Protected
  • Adjustable Current Trip Threshold (LTC7000)
  • Current Monitor Output (LTC7000)
  • Automatic Restart Timer
  • Open-Drain Fault Flag
  • Adjustable Turn-On Slew Rate
  • Gate Driver Supply from 3.5V to 15V
  • Adjustable VIN Undervoltage and Overvoltage Lockouts (LTC7000)
  • Adjustable Driver Supply VCC Undervoltage Lockout
  • Low Shutdown Current: 1µA
  • CMOS Compatible Input
  • Thermally Enhanced, High Voltage Capable 16-Lead MSOP Packages

Typical applications

  • Static Switch Driver / Load and Supply Switch Driver / Electronic Valve Driver / High Frequency High Side Gate Driver
