The LM5032MTC/NOPB is a fixed-frequency, current mode, DC/DC switching controller. It is designed to operate typically with an external N-channel MOSFET switch. This controller has advance features such as adaptive adaptive slew rate control, precursor, and input power monitoring. The device\'s non-disruptive current mode architecture, with precision 1.5% voltage accuracy and 6μA shutdown current, makes it suitable for a wide range of portable applications such as laptop computers, wireless base stations, and DSL modems.

The LM5032MTC/NOPB has a wide input operating range from 3.1V to 32V and a 3.3V output operating range. With an input voltage range of 4.5V-36V, the LM5032MTC/NOPB can provide a wide range of output voltages. It can be operated at up to 1MHz and has an integrated soft-start switch. The LM5032MTC/NOPB provides precision accuracy of +/-1.5% over the full operating temperature range.

In addition to its high accuracy, the LM5032MTC/NOPB is also capable of efficient operation with 100 mV dropout at 380 mA load. The device includes a power good pin and integrated circuitry to protect against short-circuit, undervoltage, and overvoltage conditions. It also provides programmability for frequency and current limit.

The LM5032MTC/NOPB is designed to provide a simple, low-cost solution for controlling brushed DC motor drives, such as Fan Motor Control, Wall Mount/Table/Handheld Adaptor Control, Industrial Brushless DC Motor and Digital Camera Zoom Control. It has a built-in low dropout voltage regulator (LDO), which ensures output stability.

The LM5032MTC/NOPB has two operating modes: switching frequency and sequencing timing. In the switching frequency mode, an external clock is required for an external oscillator circuit or an internal RC oscillator. In the sequencing timing mode, an external resistive element is used for start up, stop, and soft start up/shutdown control. Both of these modes are designed to help improve system reliability and minimize EMI and noise.

The LM5032MTC/NOPB is the ideal choice for a wide range applications. It can efficiently provide power to a wide range of loads, including LED backlighting, consumer electronics, industrial motor control, and appliance control.
