LT1935 Datasheet PDF - Linear Integrated System

DESCRIPTION
The LT®1935 is the industry’s highest power SOT-23 switching regulator. Its unprecedented 2A, 40V internal switch allows high output currents to be generated in a small footprint. Intended for space-conscious applications, the LT1935 switches at 1.2MHz, allowing the use of tiny, low profile inductors and capacitors 2mm or less in height. The NPN switch achieves a VCESAT of just 180mV at 2A independent of supply voltage, resulting in high efficiency even at maximum power levels from a 3V input.
