LT1534IS-1#TRPBF is a DC-DC switching regulator designed for applications such as cellular phones, camera modules, wearable devices, and other typically low-power consumer electronics. It is capable of providing up to 600mA, usually over a wide input range such as 1.8V to 5.5V. The device provides accurate, low-ripple, low-noise power for a wide range of applications. A DC-DC switching regulator is a circuit that converts a DC input voltage to a different, usually higher or lower, DC output voltage. The switching regulator is the most efficient of all the common types of DC-DC regulators due to its high frequency of operation. The LT1534IS-1#TRPBF operates in either a fixed frequency Pulse Width Modulation (PWM) mode or a Pulse Frequency Modulation (PFM) mode. The minimum input voltage (VIN_min) of the LT1534IS-1#TRPBF is 1.8V. The maximum input voltage (VIN_max) is 5.5V. The device operates at different switching frequencies depending on the input voltage, VIN. At VIN_min of 1.8V it will operate at 750kHz, while at VIN_max of 5.5V it will operate at 1.25MHz. The frequency range is wide enough to ensure the regulator will run cool, even when operating in a low-cost plastic package.The output voltage of the LT1534IS-1#TRPBF can be adjusted from 0.6V to VIN with an external resistor divider. The output voltage can also be adjusted as a function of temperature. This output voltage adjustment allows the device to be used in a variety of applications.The LT1534IS-1#TRPBF provides several features that make it suitable for a wide variety of applications, including over-voltage protection, current-limit, and thermal protection. The current limit is adjustable up to 2.5A with an external resistor. The device also includes a power save mode, which reduces consumption, and a shutdown mode, which can be controlled by an active-low logic signal.In summary, the LT1534IS-1#TRPBF is a DC-DC switching regulator designed for applications that require low power consumer electronics, such as cellular phones and camera modules. The device features an adjustable output voltage, current limit, over-voltage protection, and thermal protection. The operating switching frequency is adjustable from 750kHz to 1.25MHz depending on the input voltage, making it suitable for a wide range of applications.
