The TPS60202DGSG4 is a dual channel, 2-output synchronous switching regulator. This DCDC switching regulator offers high efficiency and low noise for end-applications requiring multiple voltage and current requirements. The device has a wide input voltage range, from 4.5V to 22V, and can output up to 3A or 10A of current, depending on the output voltage required. The TPS60202DGSG4 is programmable frequency, allowing users to adjust the frequency as required, offering maximum flexibility. The device also offers a low-noise design, with a minimum of 20mV peak-to-peak of ripple on the output.

The TPS60202DGSG4 is ideal for use in multiple applications requiring the conversion of a voltage input to multiple voltage outputs. Examples of end applications include point-of-load conversion, industrial power supplies, telecommunications systems, instrumentation, computer server and laptop power supplies, LED lighting and automotive systems. The device is used to provide either a step-down or step-up converter for an input voltage, with an output current adjustable from 0A to either 3A or 10A.

The working principle of the TPS60202DGSG4 is based on a synchronous-switched-mode PWM controller and a variable frequency current-mode control. The PWM controller provides the switched-mode signal to the external power FET, controlling the Power stage in either a step-down or step-up application. The variable frequency current-mode control has a programmable ranging from 0.7MHz to 1MHz, allowing users to customize their applications as needed. The output voltage is regulated using a feedback voltage loop. The device has a reference voltage and an internal error amplifier to set the feedback voltage loop.

The device offers a very high efficiency performance, with losses kept to a minimum, even at a high output current. The TPS60202DGSG4 also offers a low noise operation, with ripple on the output voltage being kept to a minimum of 20mV peak-to-peak. The device also has an adjustable output voltage, allowing the user to regulate the output voltage as required. It also includes a power good signal, which indicates that the output voltage is within the specified specifications. Finally, the device is also protected against reverse polarity, over temperature, and over current.

In summary, the TPS60202DGSG4 is a dual-channel synchronous-switched-mode PWM controller ideal for multiple applications requiring multiple voltage and current requirements. The device offers a wide input voltage range, programmable frequency, high efficiency, low noise, adjustable output voltage, and protective features such as reverse polarity, over temperature protection, and over current protection. This makes the TPS60202DGSG4 an excellent choice for end-applications ranging from point-of-load conversion to industrial power supplies.
