Analog Devices Inc LT1767EMS8-1.8#PBF'S Features
The LT1767EMS8 - 1.8#PBF is a highly integrated and efficient power management solution from Analog Devices Inc. It comes with a plethora of features that make it suitable for a wide range of applications. This device houses a 1.5A switch within a compact 8 - pin MSOP package, enabling it to handle relatively high - current loads in space - constrained designs. Operating at a constant 1.25MHz switching frequency, it allows for predictable and stable operation. The wide operating voltage range, spanning from 3V to 25V, makes it adaptable to various power sources, whether it's a low - voltage battery or a higher - voltage wall adapter. The internal 0.22Ω switch exhibits high efficiency, reducing power losses and enhancing overall system performance. With a fixed output voltage of 1.8V and an overall output tolerance of 2%, it provides a stable power supply for sensitive electronic components. It also uses low - profile surface - mount components, which are beneficial for applications where board space and height are critical factors.
The low shutdown current of 6µA is a remarkable feature, especially for battery - powered devices. It helps to conserve energy during standby or non - operating modes, thus extending the battery life. Moreover, the device is synchronizable to 2MHz, which can be useful for minimizing electromagnetic interference (EMI) or for integrating with other high - frequency components in a system. It also features current - mode loop control, ensuring fast transient response and excellent loop stability under different load conditions.
