Descrição geral do produto

The LM22670MRE-ADJ/NOPB is a SIMPLE SWITCHER® Step-down Voltage Regulator with synchronization or adjustable switching frequency. This voltage regulator provides all of the functions necessary to implement an efficient high voltage step-down (buck) regulator using a minimum of external components. This easy to use regulator incorporates a 42V N-channel MOSFET switch capable of providing up to 3A of load current. Excellent line and load regulation along with high efficiency (>90%) are featured. Voltage mode control offers short minimum on-time, allowing the widest ratio between input and output voltages. Internal loop compensation means that the user is free from the tedious task of calculating the loop compensation components. Available in an adjustable output voltage version and the default switching frequency is set at 500kHz allowing for small external components and good transient response.
  • Internally compensated voltage mode control
  • Stable with low ESR ceramic capacitors
  • Adjustable switching frequency and synchronization
  • Precision enable pin
  • Integrated boot-strap diode
  • Integrated soft-start
  • Fully WEBENCH® enabled
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
