LT1506IR#PBF is a range of DC-DC switching regulators from the PMIC (Power Management IC) voltage regulators class that provides high efficiency voltage conversion solutions in a tiny footprint. The regulators are designed to be used in a wide variety of applications, anything from PoE (power over Ethernet) systems, datacom and telecom power supplies, battery-powered portable devices, and distributed power architectures. With a wide input voltage range and the capability to generate output voltages up to 5.5V, the LT1506IR#PBF is the perfect choice for a wide range of DC-DC conversions.
The LT1506IR#PBF integrates a synchronous buck converter operating at peak currents of up to 2.5A, making it suitable for powering medium load applications. Output voltages are adjustable using two external resistors, or can be preconfigured to operate at a fixed output voltage of 3.3V, 2.5V, 1.8V or other commonly used voltages. The LT1506IR#PBF also has an input diode that reduces power dissipation and allows the use of wide input voltage ranges. Additionally, the device has an adjustable UVLO (Undervoltage Lockout) feature that disables the output voltage in response to abnormal input voltage conditions.}
The LT1506IR#PBF is based on a fixed frequency, peak current mode control architecture. It has built-in overvoltage and short circuit protection and is designed to produce a high efficiency output voltage over a wide input voltage range. Depending on the input voltage range, the switching frequency can be adjusted automatically, allowing the device to operate with an efficiency of up to 95%. The LT1506IR#PBF also has a number of safety features including a hiccup mode of operation if an output short circuit occurs, and thermal shutdown if an over temperature condition occurs.
The LT1506IR#PBF has a small, QFN-8N package, making it ideal for use in space-constrained applications. The device also features fast transient response and a wide input voltage range, making it suitable for a variety of applications, from solar powered systems to battery powered portable devices. The LT1506IR#PBF is also good choice for distributed power systems, as it is capable of operating from -40°C to 125°C, making it suitable for operating in harsh operating environments.
In conclusion, the LT1506IR#PBF is a highly integrated and efficient DC-DC switching regulator. It has an adjustable output voltage, wide input voltage range, fast transient response, and multiple safety features. It is also small, efficient and designed to operate in harsh environmental conditions, making it the ideal solution for a wide range of applications.
