DC–DC converters are power electronic circuits whose primary task is the conversion of a source voltage to a new value; this value may be high or low. The PSC126-7IR is a DC–DC converter specifically designed to accept a wide range of input voltages and convert it to a required output voltage with minimal power consumption. The unit is mounted in a metal chassis and has been designed for cost-effectiveness and reliability.

The PSC126-7IR is a step-up/step-down dc-dc converter that can accept an input voltage of up to 10.5 to 30 VDC and provides a regulated output voltage from 0.5 to 14 VDC at up to 8A max. It provides a high efficiency of up to 93.3%, efficiency which can be further improved by using the ECO mode; only allowing topology change on the fly instead of having to hard-reset the unit. It also has a very low standby current consumption of less than 10 mA.

The PSC126-7IR uses a control technique called pulse-width modulation (PWM) to control the output voltage. This technique is implemented in a closed-loop system, which includes a power supply and an error-amplifier (which is essentially a voltage-comparator). The error amplifier compares the desired output voltage (set by a user-adjustable potentiometer) with a reference voltage, and generates a controlling signal (in the form of a current to be used to adjust the output voltage) that will make the two values match. The power supply then modulates a pulse-width, thereby consequently changing the output voltage of the device.

The PSC126-7IR also has extensive protection features. This includes a built-in current limiting circuit, protecting against output overload or short-circuits. The device also comes with reverse voltage and under voltage protection, as well as thermal protection and brownout protection (which prevents a hazardous operation with low input voltage).

PSC126-7IR can be used in a variety of applications, including in automotive, medical, and industrial applications. It is very versatile and can be used to power a wide range of components such as LEDs, relays, microcontrollers, and motor drivers. It can be used to step-up low-voltage sources to a higher voltage or as an intermediary in a higher power system to step down a voltage from one component to another.

In conclusion, the PSC126-7IR is an efficient and economical DC–DC converter that is suitable for broad range of applications. It has exceptional features such as wide input voltage range, integrated current limiting, reverse voltage and under voltage protection, thermal protection, and brownout protection. It has a high efficiency with extremely low standby power consumption. Overall, for its price this is a very high-quality product that is sure to deliver solid performance.
