Productoverzicht

The LT3581EMSE#PBF is a PWM DC-to-DC Converter with built-in fault protection features to aid in protecting against output shorts, input/output overvoltage and over-temperature conditions. The part consists of a 42V master switch and a 42V slave switch that can be tied together for a total current limit of 3.3A. The LT3581 is ideal for many local power supply designs. It can be easily configured in boost, SEPIC, inverting or flyback configurations and is capable of generating 12V at 830mA or -12V at 625mA from a 5V input. In addition, the LT3581's slave switch allows the part to be configured in high voltage, high power charge-pump topologies that are very efficient and require fewer components than traditional circuits. The LT3581's switching frequency range can be set between 200kHz and 2.5MHz. The part may be clocked internally at a frequency set by the resistor from the RT pin to ground or it may be synchronized to an external clock.
  • Master/slave (1.9/1.4A) switch design
  • Output short-circuit protection
  • User configurable undervoltage lockout
  • Can be synchronized to external clock
  • Can be synchronized to other switching regulators
  • High gain SHDN pin accepts slowly varying input signals
  • 250mV at 2.75A Typical low VCESAT switch
