The LT1173CS8#PBF is a voltage regulator that is categorized under DC DC Switching Regulators in the PMIC (Power Management Integrated Circuit) range of products. This product converts almost any input voltage between 9V and 24V DC to a regulated output voltage of 5V DC. It provides excellent efficiency, fast transient response, low noise, wide bandwidth and low voltage stress on the output side.

The LT1173CS8#PBF has a wide variety of applications. Telecommunication appliances can make use of the LT1173CS8#PBF as its switching mode provides high efficiency and stability. The power output of the unit is ideal for automotive electronics. It can also be used in high-end industrial equipment, telecom battery chargers, medical instruments and audio amplifiers. The regulator is also designed to meet the needs of mission-critical applications such as cellular base station power supplies and telephone line interface circuits.

The LT1173CS8#PBF features a voltage step-up or step-down mode. In step-down mode, the output voltage is reduced from the source voltage to the desired value and is suitable for low-voltage applications. In step-up mode, the output voltage is increased from the source voltage to the desired value and is suitable for high-voltage applications. The switching frequency is adjustable between 200kHz and 1.2MHz to suit different application requirements.

The LT1173CS8#PBF features an active current-mode control mechanism. This mechanism allows for precise control of the output voltage and fast transient response. The maximum output current of the regulator is 4A and it can supply up to 50W of power. To minimize noise, the unit features a soft-start functional block and an internal slew-rate limit control. The output voltage is monitored by an external programmable via trimming resistors to maintain stability.

The LT1173CS8#PBF is also protected against various fault conditions like over-voltage and over-current. The short-circuit protection feature limits the output current to 100mA when a short-circuit fault is detected. The unit also has an adjustable over-temperature protection feature that shuts down the regulator if the temperature exceeds a certain limit. The maximum junction temperature of the product is 150°C.

The LT1173CS8#PBF is a highly integrated DC DC switching regulator ideal for applications that require high efficiency, low noise, wide bandwidth and low input/output voltage stress. It is versatile and suitable for many applications in the industrial, automotive and telecommunication industries. Also, its protection features enhance the overall reliability of the system.
