LD29300D2M50 is a Switching Current Mode PWM Controller produced by ON Semiconductor. It offers low standby power consumption, low input quiescent current, wide 4.5V to 42V input voltage operating range and power factor correction (PFC) functions. This makes it suitable for a variety of applications such as automotive, ac-dc and Home appliance.

The LD29300D2M50 is capable of providing fast current control and precise voltage regulation without the need for external components. It offers a wide range of online current ratio control and overvoltage protection voltage settings and enables a PFC circuit with precise current-mode control and 12V/24V output voltage range.

In terms of its application field, the LD29300D2M50 is designed for AC/DC PFC main converters, flyback converters, switched mode supplies and some other applications. To be precise, this IC can be applied to a wide range of applications such as LED lighting, home appliances, automotive, industrials and efficiency-enhanced AC/DC applications.

With regard to its working principle, the LD29300D2M50 is a switching current mode PWM controller that is built around the current-mode architecture, which has been adapted for the purpose of providing best-in-class current control and output voltage accuracy. It produces an adequate switching waveform with high frequency, low power consumption and low-noise compliance that allows for low total harmonic distortion (THD).

The controller consists of an oscillator circuit, comparators, a reset hysteresis circuitry and a voltage sensing block. The oscillator circuit generates a fixed frequency PWM output waveform from the sawtooth waveform generated by a voltage divider. The comparators compare the output waveform with the voltage output of the voltage sensing block and the reset hysteresis circuitry. The result is a regulated, precision waveform with a duty cycle that is equal to the ratio between the input and output voltages.

The LD29300D2M50 also employs a unique current-limiting feature to guarantee reliable and safe operation. This feature limits the current peak value and cycles throughout the whole period of operation by sensing the current through the low side power switch and activating this protection whenever the current reaches the set limit. This prevents over currents and allows the circuit to operate safely.

The LD29300D2M50 provides significant energy savings and protection by minimizing unnecessary losses. With its low standby power consumption, wide 4.5V-42V input voltage range and power factor correction functions, it can be a key enabler for energy efficiency optimization and provide a reliable and cost effective solution to a wide range of applications.
