DC-DC converters provide the way to convert a voltage or current level from one DC level to another. The PT78ST105V is a logic level (LLC/LPS) DC-DC converter, capable of providing higher efficiency power supply solutions for applications that require a lower output power. It operates from an input voltage range of 3-17Vin and provides a programmable output voltage range from 0.8V to 13V at 1A max. The device is designed with advanced packaging technology and is highly reliable, offering very good thermal performance for improved PCB design. The PT78ST105V is suitable for wireless and IoT applications.

Working Principle

The PT78ST105V device is based on a single switch LLC/LPS type DC-DC converter topology. The device achieves higher efficiency by regulating the output voltage through the on-time of the switching element, commonly referred to as Pulse Width Modulation (PWM). In simple terms, when the input voltage is higher than the output voltage, the switcher element is off and when the input voltage is lower, the switcher element is on. The frequency of the device can be adjusted in a range from 1MHz to 2MHz, or alternatively Synchronizable from an external clock which is useful for noise sensitive applications.

Application Field

The PT78ST105V is well suited for applications in a wide range of consumer electronics, automotive, medical and industrial markets. It is ideal for supplying power to processors, memory, FPGAs, ASICs and other low power loads. It can also be used for powering peripherals such as Bluetooth modules, LCDs, LEDs, USB devices and other similar devices. Moreover, devices used in wearable applications such as fitness trackers, smart watches, and activity monitors can also benefit from the device\'s high efficiency and low output ripple.

The device features a low shutdown current (40µA) for improved battery life in battery powered systems and adjustable under-voltage lockout (UVLO) for system productivity. Additionally, the device is protected from over-current, over-temperature and under-voltage conditions. The PT78ST105V device has a wide range of selection pins to customize its functionality according to the system needs.

In conclusion, the PT78ST105V device is an ideal choice for applications requiring efficient, and reliable operation. It is a highly versatile, low power DC-DC converter that is suitable for a wide range of applications. The device has a great feature set, and it provides flexibility for customization and tailoring for specific project needs.
