LT1944-1EMS#PBF is a high performance, high efficiency DC-DC switching regulators. It applies synchronous rectification to reduce the power dissipation and increase the efficiency. It also helps to improve light loading efficiency due to the good output filter performance. This makes the LT1944-1EMS#PBF ideal for powering low power digital circuits.

The LT1944-1EMS#PBF has an input voltage range of 2.7V to 36V and output voltage range of 0.6V to 24V. It is designed to regulate low power loads in a wide range of operating conditions, from light load efficiency to heavy load efficiency. It provides adjustable current limit, thermal shutdown and other protection. Features of this part include output voltage trim, programmable PWM frequency, adjustable soft start and over-temperature protection.

The LT1944-1EMS#PBF is a step-down switching regulator featuring a current-mode control architecture. It uses a fixed frequency PWM control which is adjustable with an external resistor. The busy compensation causes the feedback voltage to follow the output voltage, making the regulator insensitive to output voltage and loading variations. The output voltage is stable and ripple-free, thanks to the use of an external low-ESR capacitor.

The LT1944-1EMS#PBF operates with a switch current limit of 125mA, and the switching frequency can be adjusted to anywhere between 1.6 kHz and 6 kHz. A typical application of the LT1944-1EMS#PBF is to provide a stable voltage output from an unregulated input. For example, one application could be to provide a stable 5V output from a 12V automotive battery.

The LT1944-1EMS#PBF is highly reliable and provides excellent protection features, making it an ideal choice for powering high performance digital circuits. Its small package size and flexible feature set makes the LT1944-1EMS#PBF an ideal solution for a wide range of low power applications.
