DC-DC converters are devices that convert one DC current to another, or one type of DC current to a different type of DC current. The PTN78060HAH is one such device. It is a step-up DC-DC converter, meaning it produces an output voltage higher than its input voltage.

The PTN78060HAH is designed for automotive applications, where it is exposed to extreme temperatures and vibration. It is capable of handling input voltages from 6V to 42V and output voltages from 5V to 40V, and can deliver up to 9A of continuous current. The device is constructed with a surface mountable PQFN package, making it easy to install and design into automotive applications.

The electrical configuration of the PTN78060HAH is based on a push-pull topology, with fixed frequency PWM control. Inside the device, two N-channel MOSFETs are employed to drive an external inductor. The device is also equipped with internal 3v LDO regulator to provide a stable 2.5v voltage for the internal control logic.This combination creates a compact, high efficiency, high frequency switching voltage regulator. The PTN78060HAH has an efficient thermal design to minimize the external heat sink requirements in order to achieve the specified 9A output current.

The PTN78060HAH works by using the MOSFETs in a switch mode circuit. The top switch of the circuit is turned on when the voltage is below the target voltage level, allowing the inductor current to flow through it and charge the output capacitor. When the voltage reaches the target voltage level, the switch is turned off and the bottom switch is turned on, allowing the inductor current to flow through the bottom switch. This causes the current to flow back into the source and start the process all over again.

The high frequency switching of the PTN78060HAH allows it to achieve a high efficiency of up to 96%. The device has built-in over-current, over-voltage, and over-temperature protection features to ensure the safe operation of the device.The PTN78060HAH is a cost-effective solution for automotive applications, providing a high efficiency, high frequency switching step-up DC-DC converter for use in a wide variety of applications. This device is capable of providing the necessary voltage for automotive components, such as fuel pumps and lighting systems.
