The TPS51120RHBTG4 is a synchronous buck DC/DC switching controller designed for the automotive and industrial systems. It is designed to operate on a variety of input sources, including 12 V and 24 V systems. The TPS51120RHBTG4 is an ideal device for DC/DC converters that require high power and low noise, such as DC/DC converters used in automotive and industrial applications.

The TPS51120RHBTG4 features an integrated switching controller and power-on reset (POR) circuit. The device is intended for systems where continuous current is required. The device’s on-chip power-on reset circuit ensures proper POR detection for systems with large capacitors or long start-up times. The device also features thermal shutdown protection and a hysteretic thermal shutdown capacitor for operation in harsh environments. The TPS51120RHBTG4 can operate over an input voltage range of 5 V to 20 V and an output voltage range of 0.6 V to 5 V.

The TPS51120RHBTG4 has a wide operating temperature range of -40° to 85°C and is designed to meet AEC-Q100 automotive quality standards. It is available in an 8-pin thermally enhanced HTSSOP package.

The TPS51120RHBTG4 utilizes an adaptive, minimum frequency PWM control architecture, which is designed to provide high efficiency over a wide input-output voltage range. This architecture also minimizes output voltage deviations due to changing load conditions. The device uses synchronous rectification, so it does not require an external Schottky diode. This helps reduce circuit complexity and cost, while improving overall system efficiency. Furthermore, the device supports pre-bias start-up, which enables the controller to power on at an output voltage that is much lower than the input voltage.

The device also has input voltage under-voltage (UV) lockout protection and output over-current protection to ensure the safe operation of the system. In addition, the TPS51120RHBTG4 features low power mode, top-side and bottom-side gate drivers, and a single output enable pin. These features make the TPS 51120RHBTG4 ideal for a variety of automotive and industrial applications, including DC/DC converters, motor control, data communications, and system monitoring.

The TPS51120RHBTG4 is a great choice for applications requiring high power, low noise, and high efficiency. It features an adaptive, minimum frequency PWM architecture, and it does not require an external Schottky diode. It also has several protections, such as input under-voltage and output over-current protections, to ensure safe operation and reliable performance. Additionally, the device has a wide operating temperature range and meets automotive quality standards. All these factors make the TPS 51120RHBTG4 an ideal choice for automotive and industrial applications.
