Texas Instruments PTH05000WAS-DC/DC Converters

PTH05000WAS Description

The PTH05000WAS is a DC/DC converter manufactured by Texas Instruments. It belongs to the company's "wide input" series, which means that it can accept a wide range of input voltages, from 9 V to 36 V in this case.

 

The PTH05000WAS is a non-isolated step-down converter, also known as a buck converter, which means that it can output a lower voltage than its input voltage. It has a fixed output voltage of 5 V and a maximum output current of 4 A, which makes it suitable for powering a variety of electronic devices and systems.

 

This DC/DC converter uses pulse-width modulation (PWM) technology to regulate the output voltage and maintain high efficiency, up to 95% at full load. It also includes a number of features such as over-temperature protection, under-voltage lockout, and soft-start to ensure safe and reliable operation.

 

The PTH05000WAS is a high-performance DC/DC converter that offers a wide input voltage range, a fixed output voltage of 5 V, and high efficiency, making it ideal for use in a broad range of applications, from industrial control systems to consumer electronics.

PTH05000WAS Pin Descriptions

Vin: The positive input voltage power node to the module, which is referenced to common GND.

Vout: The regulated positive power output with respect to the GND node.

GND: This is the common ground connection for the ‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC reference for the ‘Inhibit’ and ‘Vo Adjust’ control input.

Inhibit: The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a lowlevel ground signal to this input disables the module’s output and turns off the output voltage. When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left opencircuit, the module will produce an output whenever a valid input source is applied.

Vo Adjust: A 0.1 W 1 % resistor must be directly connected between this pin and the GND pin to set the output voltage to a value higher than 0.9 V. The temperature stability of the resistor should be 100 ppm/°C (or better). The set point range for the output voltage is from 0.9 V to 3.6 V.

The resistor required for a given output voltage may be calculated from the following formula. If left open circuit, the output voltage will default to its lowest value.

Rset = 10 kΩ · 0.891 V/ Vout-0.9V-3.24 kΩ
