The LM20145QMHX/NOPB is a DC DC switching regulator, specially designed for high efficiency, low power applications. It provides pulse width modulated (PWM) control of output voltage and current, allowing for efficient operation over a wide output voltage range.

The LM20145QMHX/NOPB has a wide input voltage range of 6.5 V - 15 V. The device is designed to provide up to 1.5 A of continuous current and offers very low voltage dropout. The advanced PWM control scheme ensures very low input quiescent current and maintains excellent line and load regulation. This makes the device ideal for solutions requiring tight output voltage control.

The LM20145QMHX/NOPB offers an output voltage range of 0.8 V - 5 V. It is capable of generating very low output voltages with pin-selectable undervoltage lockout, allowing the device to operate at maximum efficiency while protecting the system from overloading.

The LM20145QMHX/NOPB’s on-chip error amplifier provides both line and load regulation for a wide range of input and output voltages. The pulse frequency can be programmed via an external resistor to adjust the voltage ripple, enabling designers to select the most efficient operating frequency for a given application. The device also offers an optional soft-start function, which helps to minimize input inrush currents.

The thermal performance of the LM20145QMHX/NOPB is enhanced thanks to its wide military temperature range of -55°C to 125°C. In addition, the device’s small package size makes it an ideal choice for space-constrained designs. The device is also equipped with an input-to-output voltage direct conversion capability and is rated for operation up to 85°C without a heatsink.

Applications for the LM20145QMHX/NOPB include industrial, automotive, and battery powered systems, such as LED lighting, communication systems, motor control, and battery charging. The device can also be used in applications that require very low output voltages, such as voltage and current generation for DACs, monitors, and sensors.

In summary, the LM20145QMHX/NOPB is an efficient DC DC switching regulator with wide input voltage range, low voltage dropout, and excellent line and load regulation. With its wide military temperature range, small package size, direct conversion capability, and offering of optional features, the LM20145QMHX/NOPB provides an excellent solution for high efficiency, low power applications.
