The LT1307CMS8#PBF is a high-performance, micropower step-up DC/DC converter from Linear Technology, designed to operate as a constant-frequency current mode PWM converter with a 600kHz switching frequency. This versatile component is ideal for single-cell applications due to its ability to start up with an input voltage as low as 1V and operate with an input range from 1V to 8V, making it perfect for battery-powered devices.

The LT1307CMS8#PBF is housed in an 8-lead MSOP package, which provides a compact footprint suitable for space-constrained applications. Its high switching frequency enables the use of small, low-cost capacitors and inductors, further minimizing the size and cost of the overall power supply design.

Key features of the LT1307CMS8#PBF include its low quiescent current, typically 20µA, which helps to maximize battery life in portable applications. The device also includes a low-battery detector that can be programmed to indicate when the battery voltage falls below a user-specified threshold. Additionally, the converter offers an automatic shifting to power saving mode at light loads, which reduces the quiescent current to only 5µA, further extending battery runtime.

The LT1307CMS8#PBF provides a high level of integration with internal switches and diodes, which simplifies the design process and reduces external component count. Its current mode operation provides excellent transient response and cycle-by-cycle current limiting, enhancing the safety and reliability of the system. The device also features a shutdown mode that reduces the supply current to 0.5µA, which is beneficial for preserving battery life when the device is not in use.

With its robust feature set and high efficiency, the LT1307CMS8#PBF is an excellent choice for a wide range of applications, including cellular phones, medical and healthcare equipment, wireless and portable devices, and other battery-operated systems that require an efficient power conversion solution.
