Linear Technology LTC1982ES6: A Compact, High-Efficiency Switched Capacitor DC/DC Converter

The LTC1982ES6 from Linear Technology is a versatile and highly efficient switched capacitor DC/DC converter that is designed to provide a compact power management solution for a wide range of applications. Its small footprint and high efficiency make it an ideal choice for portable and battery-powered devices where space is at a premium and energy efficiency is crucial.

The LTC1982ES6 operates over a wide input voltage range of 1.8V to 5.5V, making it compatible with various power sources, including single-cell lithium-ion batteries. It can deliver a regulated output voltage that is either doubled or inverted from the input voltage, which provides designers with flexibility in managing power supplies within their circuits.

This converter is housed in a compact 6-lead SOT-23 package, ensuring minimal impact on the overall size of the end product. Despite its small size, the LTC1982ES6 does not compromise on performance. It boasts high conversion efficiency, thanks to its low quiescent current and the use of low-loss switching capacitors.

Furthermore, the LTC1982ES6 features a low-noise operation, which is critical for sensitive RF and analog applications. The device's switching frequency is set internally, which reduces the need for external components and simplifies the design process. It also has built-in short-circuit and over-temperature protection, enhancing the reliability and safety of the end product.

The LTC1982ES6's ease of use is exemplified by its minimal external component requirement. Only two flying capacitors and two small bypass capacitors are needed to complete the design, which helps to reduce the overall cost and complexity of the power supply circuitry.

In summary, the LTC1982ES6 from Linear Technology is a high-efficiency, switched capacitor DC/DC converter that offers a compact and flexible solution for power management in space-constrained applications. Its wide input voltage range, high efficiency, low noise operation, and ease of use make it a top choice for designers looking to optimize their power supply designs.
