AS1331-BTDT-25 is a DC-to-DC switching regulator developed by ASix Inc. The device improves power efficiency, delivers robust power supply, and increases reliability of network products. The device features a high conversion efficiency, high accuracy, excellent thermal performance, low output ripple, and low input/output cross regulation.

The DC-to-DC switching regulator is widely used in electronic modules such as Power over Ethernet (PoE), Ethernet switch, router, Customer Premises Equipment (CPE) and more. It can cater to the stringent current requirements posed by applications that require high accuracy and scalability. The device supports a wide input voltage range from 4.5V to 36V and its 15-bit programming input allows a wide configuration range.

The AS1331-BTDT-25 offers accurate voltage regulation for digital platforms. It identifies, measures and regulates the voltage output to ensure reliable voltage. It is made of high performance MOSFETs and provides high conversion efficiency, low output ripple, excellent thermal performance, and high accuracy. In addition, the device features overvoltage and overcurrent protection, provides significant power dissipation and enables low standby mode efficiency.

The AS1331-BTDT-25 serves as a power solution for applications that require robust, flexible and reliable power supply. Its wide operating temperature range allows the device to meet varying temperatures in industrial and networking applications. The device also provides short circuit protection which is designed to protect against output overload and short circuits.

The device works through the principle of buck,boost and buck-boost converters. It operates with a high speed PWM (pulse width modulation) to deliver low output noise and better system efficiency. When the output voltage is higher than the input voltage, the device works as a buck converter and converts the output voltage to the lower desired level. On the other hand, when the input voltage is higher than the output voltage, the device works as a boost converter and delivers the desired output voltage.

The device can also regulate output voltage as a step-down buck-boost converter when the input and output voltage is equal. In this case, the device uses PWM to implement soft start and it can also offer preset overcurrent protection. Additionally, the device can be used as a buck-boost controller with external switches.

The AS1331-BTDT-25 is designed to provide a highly efficient, flexible and reliable power solution to systems requiring robust power supply. It features a wide input voltage range, excellent thermal performance, low output ripple, and low input/output cross regulation. It can be widely used in applications such as Power-over-Ethernet modules, Ethernet switches, customer premise equipment, and more.
