TPS59620RHAR is a high-performance special purpose voltage regulator designed for use in supplies with a range of input voltages. It can be used for applications requiring regulated output voltages of up to 20V and higher. The device is capable of providing an output current of up to 1A and has an ultra-low voltage dropout of less than 0.8V at 1A load current. The unique feature of this device is the drive control feature that is used to synchronize multiple devices into a single system. Application Field The TPS59620RHAR can be used in high efficiency, low noise and low dropout 3V to 20V systems. It is suitable for applications where a low noise, high efficiency, low regulation, and high current drive are required. It can be used in automotive, industrial, consumer, medical, and computing applications.The device is well suited for applications such as battery-powered systems, smart phones and tablets, digital telecom, portable navigation systems, medical equipment, and embedded computing applications. It can be used to provide a regulated output voltage from the input rail. It can also be used in point of load, LED drivers, handheld radios, and instrumentation applications. Working Principle The TPS59620RHAR is a single-phase synchronous rectifier buck-converter. It operates by converting a DC voltage input to a DC voltage output. The device operates by switching a MOSFET on and off at a constant frequency and with a variable duty cycle. The duty cycle of the switch is adjusted to maintain the desired output voltage. The output voltage is then regulated by comparing the output voltage to an internal reference voltage and adjusting the duty cycle of the switch accordingly. The reference voltage is provided by an internal low-dropout voltage regulator.The device also includes a drive control feature, which allows multiple devices to be synchronized in a single system. The drive control provides a master reset signal, which is used to reset the duty cycle of all the devices. This drive control feature eliminates the need for the external control signals and allows the devices to be synchronized in a single system.The device also features overcurrent protection, thermal shutdown, and overvoltage protection. The device has an under-voltage lockout (UVLO) circuit which prevents the device from operating during low-voltage conditions. The device also has a start-up circuit that allows the device to start up at low voltages, such as a battery system.
