This voltage regulator is capable of delivering output voltages between 0.9V and 5V, with a maximum output current rating of 13A. It can be used in a variety of applications, such as battery-operated systems, low profile power supplies, smartphone power management, and other high-efficiency applications.

Working Principle

The E-L4971D013TR voltage regulator uses a pulse width modulation (PWM) control scheme to regulate outputs. It modulates the relationship between input voltage and output voltage and current by controlling the duty cycle of the signal. The signal is generated by a current-sensing comparator, which switches the base transistor of the error amplifier on and off to regulate the output voltage. The signal is output with bipolar control technique and synchronized clock, which allows the voltage regulator to operate in different modes.

When the feedback voltage is lower than the reference voltage, the output will be increased by the controlling signal from the PWM control stage. When the output exceeds the reference voltage, the output will be decreased. The peak voltage or current can be set by altering the clock frequency, which is constantly adjusted based on the environmental conditions. This allows the voltage regulator to remain adaptive to any changes, thus maintaining the desired power output.
