PMIC - AC DC Converters, Offline Switchers is a common power device that comes in a variety of designs. From milli-watts to kilo-watts of power, and with a range of input and output voltages, the PMIC - AC DC Converters, Offline Switchers are the mainstay of the power industry. One particular type is the TNY375GN, which is a versatile, low-voltage synchronous rectified, buck-converter with an internal MOSFET. This is a highly reliable device with excellent noise immunity characteristics, and it is designed to be used in a wide variety of low power applications such as Telecom, Automotive, Portable Electronics, Industrial, and Medical equipment.

The TNY375GN is a three-terminal buck-type switching regulator with an input voltage range of 3.2V to 16V and an output voltage range of 0.8V to 5V. It features a high efficiency >95% and a wide operating frequency range of 200KHz to 1. 5MHz. The device is capable of delivering up to 2.5A of continuous current with an internal MOSFET switch and protected by an external output current-sensing resistor. It also features programmable synchronization input and dynamic voltage positioning.

The main feature of the TNY375GN is its very low quiescent current. This makes it suitable for applications which require long-term energy-saving. Furthermore, its very low standby power consumption makes it ideal for portable devices and equipment where long battery life is paramount.

The TNY375GN circuit consists of several components that interact in such a way that the desired output voltage can be achieved. The main components of the circuit are the error amplifier, the gate driver, the power MOSFET, a few capacitors, and a few resistors. The error amplifier senses the difference between the desired output voltage and the actual output voltage. When an error is detected, it sends the signal to the gate driver, which then switches the MOSFET at the given frequency.

The switching of the power MOSFET can be automatically synchronized to a given frequency by connecting the SYNC pin to the external oscillator. This feature allows the design of high-efficiency synchronous buck converters when a precise frequency is required. The dynamic voltage positioning feature of the TNY375GN allows precise output voltage settings to be applied by controlling the voltage on the FB pin. This pin can be connected to a microcontroller or an analog voltage reference.

The TNY375GN is an efficient and reliable device that can be used in a wide range of low-power applications. Its quiescent current and standby power consumption is very low, making it ideal for long battery life applications. It is also highly programmable and can be used for synchronization and dynamic voltage positioning applications. With its wide voltage range, its high efficiency, and its reliable operation, it is well suited for use in a variety of low-power equipment and devices.
