LM2733 - Boost Converters

General Description

The LM2733 switching regulators are current-mode boost converters operating fixed frequency of 1.6 MHz (“X” option) and 600 kHz (“Y” option).

Key Features

  • 1 40-V DMOS FET switch.
  • 1.6-MHz (“X”), 0.6 MHz (“Y”) Switching frequency.
  • Low RDS(ON) DMOS FET.
  • Switch current up to 1 A.
  • Wide input voltage 2.7 V to 14 V.
  • Low shutdown current (< 1 µA).
  • 5-Pin SOT-23 package.
  • Uses tiny capacitors and inductors.
  • Cycle-by-cycle current limiting.
  • Internally compensated 2.
