DC-DC converters offer a variety of advantages over traditional AC/DC converters, including increased efficiency, reduced size and weight, and improved conversion accuracy. The PT4821N is a regulated, high-efficiency, low-current single-channel DC/DC converter with a wide range of operating voltages and efficiencies. This high-performance DC/DC converter offers up to 2.0W in a compact 5mm x 5mm package. It is designed for use with a wide input voltage range from 2.7V to 24V, allowing it to work with a variety of power sources. The device also offers high-efficiency and low quiescent current in a wide temperature range and under a broad range of loads. The PT4821N utilizes a constant frequency synchronous buck switching regulator topology to produce a regulated output voltage without the need for an external transformer. This topology includes an integrated P-channel power MOSFET, switching on the low-side of the circuit. The regulating comparator senses the output voltage of the converter and feeds the feedback signal back to the internal digital controller, which modulates the P-channel power MOSFETs duty cycle to regulate the output voltage. This device includes input, output, and on-chip over-current protection. It also features low supply current, low start-up current and low drop-out voltage, making it suitable for applications where power-level and low-power consumption are critical. The device is also equipped with a Power Good output indicator, which can be used to provide a signal when the output voltage is within normal limits. The PT4821N can be used in a wide range of applications including battery charging, factory automation, automotive, telecom, industrial control systems, and many more. Its small size makes it ideal for use in space-constrained systems. With its wide input voltage range, high efficiency, and fast switching speed, this converter is a great choice for high-performance applications.
