LTC1682IMS8-5#PBF - High Efficiency, Low Noise Doubler Charge Pump

The LTC1682IMS8-5#PBF is a versatile and high-performance charge pump voltage doubler produced by Linear Technology, which is now part of Analog Devices. This device is designed to provide a compact and efficient solution for generating a regulated output voltage that is twice the input voltage, with an input range from 2.7V to 4.5V. It is particularly suitable for applications that require a low-noise, positive voltage from a single lithium-ion battery or other similar power sources.

This charge pump features a low quiescent current and operates with a high switching frequency that allows for the use of small, low-cost capacitors while still providing a low output voltage ripple. The LTC1682IMS8-5#PBF is ideal for portable applications where space and power efficiency are critical, such as handheld medical devices, personal digital assistants (PDAs), mobile phones, and other battery-powered electronics.

The device is housed in a compact MSOP-8 package, which is suitable for space-constrained applications. The LTC1682IMS8-5#PBF includes a low-battery detector that signals when the input voltage falls below a preset threshold, ensuring reliable operation of the connected device. Additionally, it features thermal shutdown and current limit protections to safeguard the device under abnormal operating conditions.

Key features of the LTC1682IMS8-5#PBF include:

• Regulated Output Voltage: 2 x V<sub>IN up to 5V
• Input Voltage Range: 2.7V to 4.5V
• Low Output Voltage Ripple
• High Switching Frequency: 1MHz
• Low Quiescent Current
• Thermal Shutdown and Current Limit for Device Protection
• Low-Battery Detector
