The TPS40195PWR is a DC-to-DC switching controller, specifically designed for use in multiple-channel, intermediate distributed-power architectures, such as notebook PCs, servers and mobile products. This 9-pin integrated circuit is capable of synchronizing the voltage regulation of up to four isolated buck, boost and/or inverting output channels, while operating from an ultra-wide input voltage range of 2.7V to 28V. The TPS40195PWR offers an adjustable switching frequency range of up to 3.2MHz, making it an ideal power management solution for high frequency applications operating over a wide input voltage range.

The TPS40195PWR can be implemented in a variety of ways, such as with a single couple of buck/boost channels, or with an independent pair of buck/boost output channels and a separate inverting output channel. The controller offers an adjustable DCR-mode of current regulation which provides low output voltage ripple, low EMI and improved transient response, particularly in buck regulator applications. The TPS40195PWR also features auto-fault recovery, as well as over-current and over/undervoltage protection.

In terms of its application field, the TPS40195PWR is primarily used in mobile and distributed power supply systems and DC-DC switching regulators. It works well in battery powered systems such as laptops, tablets, servers and any other product that uses an intermediate power system. The driver can easily handle input and output voltages ranging from 2.7V to 28V, which makes it an ideal solution for applications operating with a wide input voltage range. The device also offers an adjustable frequency range of up to 3.2MHz, so it can be used in high frequency applications.

The TPS40195PWR’s working principle is based on a combination of the ON/OFF control of power switches and current mode control. It has an internal oscillator that can be adjusted using an external resistor, and the output voltage can be programmable using an external resistor. Its ON time and pulse width can also be adjusted with an external resistor. The device also features auto-fault recovery, as well as over-current and under/overvoltage protection to ensure reliability and safety.

The TPS40195PWR is a highly-advanced and reliable DC-DC switching controller. It offers an adjustable frequency range of up to 3.2MHz, while operating from an ultra-wide input voltage range of 2.7V to 28V. The device is ideal for use in high frequency applications operating over a wide input voltage range. It also features auto-fault recovery, as well as over-current and over/undervoltage protection, making it an ideal power management solution for battery-powered systems such as laptops, servers and mobile devices.
