The LTC1682CMS8#TRPBF from LT is a versatile doubler charge pump integrated circuit featuring an internal low noise, low dropout (LDO) linear regulator. This device is engineered to deliver a clean, boosted supply voltage, making it ideal for powering noise-sensitive components such as high-frequency VCOs in wireless applications.
Key electrical specifications include a wide input voltage range of 1.8V to 4.4V and the capability to supply up to 50mA of output current. The charge pump operates at a 550kHz switching frequency, contributing to its efficiency. The LDO regulator offers low output noise of 60µVRMS (100kHz BW) and is stable with as little as 2µF on the output, allowing for the use of small ceramic capacitors to save board space.
Available in fixed 3.3V and 5V versions, as well as an adjustable version with an output voltage range of 2.5V to 5.5V, the LTC1682 series offers flexibility for various designs. The device also features low operating current of 150µA and a low shutdown current of 1µA. For protection, it includes internal thermal shutdown and current limiting.
The LTC1682CMS8#TRPBF is supplied in an 8-pin MSOP package, suitable for surface mount applications. Its design considerations include the use of small ceramic capacitors and no requirement for external inductors, simplifying circuit design and reducing component count.
The output noise is 60µVRMS with a 100kHz bandwidth.
The adjustable output voltage range is 2.5V to 5.5V.
The fixed output voltage options are 3.3V and 5V.
The input voltage range is 1.8V to 4.4V.
The LTC1682 can supply up to 50mA of output current.
The switching frequency is 550kHz.
The operating current is 150µA.
