Micropower Regulated 3.3V/5V Charge Pump

The LTC1754 is a micropower charge pump DC/DC converter that produces a regulated output. The input voltage range is 2V to 4.4V for a 3.3V output and 2.7V to 5.5V for a 5V output. Its extremely low operating current and minimal external component requirements (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the LTC1754 ideally suited for small, battery-powered applications. The total component area of the application circuit is only 0.052 square inches. The LTC1754 operates as a Burst Mode switched capacitor voltage doubler to produce a regulated output. It features thermal shutdown capability and can withstand a continuous short circuit from VOUT to GND. The LTC1754 is available in a 6-pin SOT-23 package. Pricing is for budgetary use only and is subject to change. International prices may vary due to local duties, taxes, fees, and exchange rates. For volume-specific pricing or delivery quotes, contact a local Linear Technology sales office or authorized distributor. Linear Technology also offers demo boards free of charge to qualified customers. Contact your local sales office or distributor for inquiries about demo boards. Certain demo boards are available for purchase via credit card on the website and are intended for evaluation purposes only. It is the customer's responsibility to verify the proper and reliable operation in the actual end application.

The LTC1754 is designed as a micropower charge pump DC/DC converter, ideal for applications requiring a regulated output while operating with low power consumption. The device accepts an input voltage ranging from 2V to 4.4V for generating a 3.3V output, and from 2.7V to 5.5V for a 5V output. The architecture of the LTC1754 utilizes a Burst Mode switched capacitor voltage doubler configuration, which allows it to efficiently convert voltage while maintaining low quiescent current.

The minimal external component count is a significant feature of this device, requiring only one flying capacitor and two bypass capacitors for input and output stabilization. This simplicity contributes to a compact footprint, with the total component area measuring just 0.052 square inches, making it particularly suitable for small, battery-operated devices.

The LTC1754 includes built-in thermal shutdown protection, enhancing reliability in adverse conditions by preventing overheating. It is also capable of surviving a continuous short circuit from the output to ground, safeguarding the device and the circuit it powers.

Housed in a 6-pin SOT-23 package, the LTC1754 is designed for ease of integration into various electronic systems. Pricing information is provided for budgetary purposes and may vary based on location and market conditions. For detailed pricing, availability, and demo board inquiries, customers are encouraged to reach out to local Linear Technology representatives or authorized distributors. The demo boards serve as valuable tools for evaluating the LTC1754's performance in real-world applications, although users must confirm the device's operational reliability in their specific implementations.The LTC1754 is a micropower charge pump DC/DC converter that produces a regulated output.
