The LTC3335IUDC#PBF is a specialized integrated double buck synchronous DC-DC switching regulator. It is a highly efficient voltage regulator circuit that allows efficient operation in situations where the power consumption of the circuit is low or moderate. It is designed to operate in a wide range of applications, from small components such as handheld devices to larger ones like computers.
An important feature of the LTC3335IUDC#PBF is that it combines two synchronous buck regulators. Each of these can provide independent output voltage regulation, which allows the device to be used in a wider range of applications. This device also has a wide input voltage range, ranging from 4.5 to 32 Volts.
The LTC3335IUDC#PBF is built around a high-frequency voltage conversion circuit, using synchronous buck regulators leading to a lower total power dissipation. It allows the regulator to be used in applications that require both efficiency and low voltages, without sacrificing performance.The device provides fast transient response and has excellent line and load regulation.
The power conversion efficiency of the LTC3335IUDC#PBF is typically greater than 90%. The switching frequency of the device can be adjusted from 100 kHz to 1 MHz, allowing for greater current conversion efficiency. Moreover, the device allows for adjustment of the loop compensation, so that the device can be used in applications with different output requirements.
The LTC3335IUDC#PBF has been designed to be used on many types of applications, from single cell Li-ion battery to multifunctional systems with multiple sources. It is suitable for powering a variety of devices such as mobile phones, PDAs, GPS receivers, LCD panels, and a variety of consumer electronic devices.
The working principle of the device is that it provides two buck synchronous voltage regulators working together to achieve a constant output voltage. The first regulator, the primary output regulator, operates on the actual input voltage to provide a regulated output voltage. The second regulator, the secondary output regulator, is used to maintain a second output voltage if a higher output voltage is required. The two regulators are controlled by the same clock signal to start and stop, and to maintain the required output voltage.
The LTC3335IUDC#PBF has the advantage of high efficiency, low power dissipation, wide input voltage range and fast transient response. It can be used in a variety of applications and provides excellent line and load regulation. The wide operating frequency range and adjustable loop bandwidth allows the device to be used for various output levels, making it an ideal choice for a variety of high-performance, low-power applications.
