The LM2738YSD/NOPB is a DC DC switching regulator PMIC (Power Management IC). It offers greater flexibility in developing control systems for varied applications. It is designed to provide efficient voltage regulation and current limiting for steady state and start-up operations.

The LM2738YSD/NOPB integrates a low-noise linear regulator, power amplifier, error amplifier, ramp compensation, PWM comparator, and current sense and fault detection circuitry into a single integrated circuit. This device can be used in a variety of applications that require efficient voltage regulation and current limiting.

The LM2738YSD/NOPB can be used in various applications that require high-efficiency levels. It can also be used for such applications as digital telecommunications, networking systems, distributed power architectures, and power line communications. The device is designed to operate as low as 0.5 V, providing flexibility to design and build systems that support higher efficiency designs.

The LM2738YSD/NOPB has a built-in linear error amplifier, which provides the signal conditioning for buck or boost mode operation. The adjustable error amplifier affords fine-tuning of the output voltage and current limiting operation. The device also provides for high resistance low quiescent current stop, sync and latch circuits. This device is compatible with all types of switching power supplies.

The LM2738YSD/NOPB supports a programmable operating range of 0.7V to 16 V output voltage and can supply up to 25 A of current at an efficiency rating of 94%. The over-current trip point and hysteresis range can be programmed using external resistors. In addition, the device features internal current limiting, load sense and reset circuitry. The device also features built-in over-voltage protection, over-temperature protection, and under-temperature protection.

The LM2738YSD/NOPB has a very low quiescent current of less than 1 μA. The device also supports start-up mode, which enables the device to be turned on quickly when it is connected to the input voltage for the first time. The output voltage is kept at a constant level, allowing for a constant output voltage when transitioning from the start-up mode to the steady-state mode. It also supports a sleep mode, which allows the device to turn off quickly when the output voltage drops below the set value. This mode can be used to save battery power.

The LM2738YSD/NOPB has several features to improve the performance of the system, such as frequency dithering, phase spreading and voltage folding. Frequency dithering reduces the overall ripple on the system. Phase spreading reduces the peak current load on the switching device, while voltage folding helps to reduce the overall losses in the system. The LM2738YSD/NOPB also provides a wide input voltage range of 4.5 V up to 24 V.

Overall, the LM2738YSD/NOPB is an integrated power management IC (PMIC) suitable for a variety of applications that require efficient voltage regulation and current limiting. Its low quiescent current, start-up mode, enhanced operating range and frequency dithering, phase spreading and voltage folding features make it a great choice for power systems.
