The LTC1504ACS8-3.3#PBF is a DC/DC switching voltage regulator from Linear Technology\'s family of advanced PMIC (power management integrated circuit) products. It is designed to provide high-efficiency and a constant output voltage in a wide range of DC/DC supply designs, making it ideal for a variety of applications, including automotive, industrial, and consumer electronics.
The LTC1504ACS8-3.3#PBF is an 8-channel step-down DC/DC switching regulator designed for applications where high current and a wide voltage range are required. It has an adjustable output voltage ranging from 0.6V to 3.3V, making it ideal for powering FPGAs and ASICs. The device also features internal synchronous rectifiers, DC/DC compensation circuit, and low dropout linear regulator circuitry.
The LTC1504ACS8-3.3#PBF is optimized for efficiency, providing up to 95% efficiency at low load and up to 96% efficiency at moderate loads. This helps to reduce energy costs, improve system performance, and increase system reliability. It also features over-current protection and short-circuit protection, which helps to protect against accidental overloads.
The LTC1504ACS8-3.3#PBF can be used in a variety of DC/DC supply designs, including buck, boost, and buck-boost topologies. The device works by converting a DC input voltage to an adjustable output voltage. In buck power supplies, the input voltage is converted to a lower output voltage, while in boost supplies, the voltage is increased. In buck-boost supplies, the voltage is both increased and decreased.
When operating in buck mode, the LTC1504ACS8-3.3#PBF uses an internal switching control circuit to regulate the output voltage. The device is capable of switching at frequencies up to 1MHz, allowing for a small physical footprint and low noise operation. The device features an adjustable output voltage and over-voltage protection with hysteresis, ensuring the output will maintain a consistent voltage level.
In boost configurations, the internal circuit of the LTC1504ACS8-3.3#PBF switches the output voltage to a higher level than the input voltage. This enables the device to compensate for voltage losses due to cabling and other losses in the system. The device has a minimum input start voltage of 3.3V and provides a maximum output voltage of 15V and a maximum current capacity of 6A.
The LTC1504ACS8-3.3#PBF is also capable of operating in buck-boost mode. In this configuration, the device is capable of regulating the output voltage below and above the input voltage. This allows for the device to be used in applications where the input voltage is unstable or there is an output voltage above that of the input voltage.
The LTC1504ACS8-3.3#PBF from Linear Technology offers a complete package of DC/DC switching voltage regulator solutions for a variety of applications. With a wide input voltage range, high current capacity, over-voltage protection and 95% efficiency, it is an ideal choice for automotive, industrial, and consumer electronics applications, as well as for powering FPGAs and ASICs.
