AC/DC converters are devices that convert alternating current (AC) into direct current (DC) or vice versa. They are widely used in a variety of applications including power supplies, industrial automation, and medical equipment. The TIS 300-148 is one such converter, that makes use of pulse width modulation (PWM) to control the output voltage and current.

The TIS 300-148 is a high-efficiency DC/DC converter, which features a maximum peak efficiency of 91%. It is capable of operating from a wide input voltage range of 4.5 V to 15 V, with an output voltage of 5 V. The output current is adjustable from 0.1 A to 3 A, and the maximum power output capacity is 15 W. It also features over-voltage, over-temperature and short-circuit protections to ensure system safety in any operation.

The TIS 300-148 implements PWM to provide superior performance. The internal control circuit of the device generates a triangle wave oscillating signal, and the triangle wave is compared with a reference voltage to produce a duty cycle signal. The duty cycle signal is then used to control the output voltage. The frequency of the triangle wave can be adjusted by an external resistor, allowing for a wide range of control and output voltage stability.

The TIS 300-148 also provides users with various features to improve system efficiency. For example, the device uses "Burst Mode" to improve light load efficiency. It can also be disabled by shorting the SYNC pin to the input voltage. In addition, the device can be used in combination with an external voltage regulator to maximize efficiency at higher load currents.

In summary, the TIS 300-148 is a high-efficiency, low-cost DC/DC converter that is suitable for use in many applications. It can provide a stable output voltage with excellent load and line regulation, and its high efficiency makes it an attractive option for those who need to conserve power and keep energy costs low.
