DC DC Converters are used to convert direct current from one voltage to another. The SUW62415C is a single-channel, high-speed, small size DCDC buck converter. It features a high efficiency, a wide input voltage range and a wide output voltage range.

The SUW62415C is intended for use in a wide range of applications, such as data centers, telecom equipment, servers,storages,industrial applications, and consumer products, where power efficiency and flexibility are paramount. It operates over a wide input voltage range of 4.5V to 15V and provides an adjustable output voltage range of 0.6V to 5.5V. The output voltage is adjustable via an on-board DAC or external voltage.

The SUW62415C has a wide operating temperature range from -40°C to + 125°C, and features power-saving capabilities to maximize efficiency and optimize the thermal performance. The device is capable of delivering an output switch current up to 5A with a fast loop response time of 35ns. It also offers programmable protection features, such as under-voltage protection, over-voltage protection, over-current protection and over-temperature protection.

The SUW62415C operates by converting the input voltage to the output voltage through a series of switch-mode steps. The device uses a hysteretic control loop that regulates the voltage on the output of the DC/DC converter, measuring the output voltage via the built-in feedback voltage divider and then applying a bias to the current-sense amplifier. Then, the device will compare the output voltage with the desired output voltage, and if the output voltage is lower than the desired voltage, the device will turn-on a current switch OpAmp to increase the current and raise the output voltage. The current switch OpAmp will then turn off when the output voltage reaches the desired voltage. The current switch OpAmp will repeat this on/off process continually, regulating the output voltage. The device also has a shutdown control logic, which allows for flexibility when in a power-saving mode.

The SUW62415C has a wide input voltage range, a wide output voltage range, and a high efficiency, making it an ideal DC/DC converter for a variety of applications. It is also capable of delivering high output switch currents with low quiescent currents, and it includes a range of powerful protection features, ensuring robust operation.
