LTC1682IMS8-3.3 - High Efficiency, Low Noise Doubler Charge Pump

The LTC1682IMS8-3.3 is a high-performance, low noise, regulated charge pump voltage doubler produced by Linear Technology. This device is designed to provide a space-efficient and efficient power solution for applications requiring a low voltage input to be doubled with minimal ripple and noise. It is particularly suitable for battery-powered devices, portable equipment, and other low-voltage applications where extended battery life and low noise are critical.

Featuring a wide input voltage range of 2.7V to 4.5V, the LTC1682IMS8-3.3 can deliver a fixed output voltage of 3.3V with an output current up to 30mA. This makes it an ideal choice for systems operating from single-cell lithium-ion batteries or other low voltage power sources. The device's high switching frequency of 900kHz allows the use of small, low-cost capacitors while maintaining low output voltage ripple.

The LTC1682IMS8-3.3 incorporates Linear Technology's proprietary low noise charge pump technology, which significantly reduces the voltage ripple and electromagnetic interference (EMI), ensuring a clean and stable power supply. This is particularly important in sensitive RF and audio applications where power supply noise can adversely affect performance.

In terms of protection features, the LTC1682IMS8-3.3 includes thermal shutdown and current limiting to safeguard the device and the load from adverse conditions. Furthermore, its low quiescent current makes it an excellent choice for battery conservation in standby and low power modes.

The LTC1682IMS8-3.3 is available in an MS8 package, which is a small outline, surface-mount package, making it suitable for space-constrained applications. Its compact size and low profile contribute to a reduced PCB footprint, facilitating the design of compact and lightweight electronic products.

To summarize, the LTC1682IMS8-3.3 from Linear Technology is a reliable and efficient solution for doubling a low voltage input with minimal added noise, ideal for portable applications where power efficiency and noise performance are of paramount importance.
