The LT1935 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.
A constant frequency, internally compensated, current mode PWM architecture results in low, predictable output noise that is easy to filter. Low ESR ceramic capacitors can be used on the output, further reducing noise to the millivolt level. The high voltage switch on the LT1935 is rated at 40V, making the device ideal for boost converters up to 38V as well as for single-ended primary inductance converter (SEPIC) and flyback designs. The device can generate 5V at up to 1A from a 3.3V supply or 5V at 550mA from four alkaline cells in a SEPIC design.
The LT1935 is available in a 5-lead SOT-23 package.
