Features and Benefits
- 1.3MHz (LT3460) Switching Frequency
- 650kHz (LT3460-1) Switching Frequency
- High Output Voltage: Up to 36V
- 300mA Integrated Switch (LT3460)
- 180mA Integrated Switch (LT3460-1)
- Wide Input Range: 2.5V to 16V
- Uses Small Surface Mount Components
- Low Shutdown Current: <1μA
- Low Proﬁle (1mm) SC70 (LT3460 and LT3460-1), SOT-23 (ThinSOT™) (LT3460) and 2mm × 2mm DFN (LT3460-1) Packages
The LT3460/LT3460-1 are general purpose step-up DC/DC converters. The LT3460/LT3460-1 switch at 1.3MHz/ 650KHz, allowing the use of tiny, low cost and low height capacitors and inductors. The constant frequency results in low, predictable output noise that is easy to ﬁlter.
The high voltage switches in the LT3460/LT3460-1 are rated at 38V, making the device ideal for boost converters up to 36V. The LT3460 can generate 12V at up to 70mA from a 5V supply.
The low 1mA quiescent current and 650kHz switching frequency of LT3460-1 make it ideal for lower current applications.
The LT3460 is available in SC70 and SOT-23 packages. The LT3460-1 is available in SC70 and 2mm × 2mm DFN packages.

Evaluation Kits (1)
Demonstration circuit 545 features the LT3460, step-up DC/DC converter with 1.3MHz constant frequency in a SC70 package. There are two switching regulator circuits in DC545. The 12V output boost converter (upper circuit) is designed to convert 5V input to 12V output at 70mA of load current and the SEPIC converter (lower circuit) is designed to convert 10V ~ 16V input to 12V at 50mA.
