PT4827A

DC-DC converters convert direct current (DC) from one voltage level to another. They are often used to power electronic appliances and vehicles. The PT4827A is a type of DC-DC converter developed by PowerTune, a Panasonic business. This product is a high performance solution for many applications that require efficient power conversion.

The PT4827A features a wide range of input voltages, from 4.5V to 36V, with a maximum output current of 2A. It has an ultra-fast input rising time of 50µs, with a minimum duty cycle of 8%. It also supports higher input and output voltages, with a maximum output voltage of 90V. With its high frequency PWM control, the PT4827A is suitable for a variety of applications.

These applications include point-of-load converters, distributed power systems, motor drivers, battery-powered devices, embedded systems, telecom systems, and power distribution networks. With its wide input voltage range, high output current, and low EMI, the PT4827A is ideal for powering high-speed, low-power applications such as digital signal processing and analog systems.

The PT4827A is designed to operate on a high frequency pulse width modulation (PWM) control architecture. This allows the device to operate with higher efficiency and eliminates the need for a bulky inductor in the output stage. The internal circuitry monitors the output voltage and adjusts the PWM duty cycle accordingly to maintain the output voltage stability.

In addition, the PT4827A has a dedicated current-sense input. This allows for current limiting and over-current protection, which helps to ensure safety in power-transmission applications. The PT4827A also features adjustable soft-start, short-circuit protection, current limit fold back, and over-temperature protection.

The PT4827A is a reliable and efficient DC-DC converter. With its wide operating range, high frequency PWM control architecture, and advanced features, it is suitable for a variety of applications. It offers superior performance and is ideal for applications that require efficient power conversion.
