LMR23630APDRRR Application Field and Working Principle

The LMR23630APDRRR Voltage Regulator is a DC-DC switching regulator that delivers high-efficiency and cost-effective performance. This family of regulators is designed to accept input voltage ranging from 3.3 V to 48 V and provide output voltage of 0.6 V to 24 V. It requires an external inductor and output capacitors for proper operation.

The LMR23630APDRRR is well-suited for point-of-load (POL) applications and high current applications up to 6.25 A at 4.5V input. The device features current mode control that provides programmable switching frequency of up to 2.2 MHz enabling fast transient response. It also includes programmable soft-start, undervoltage lockout with hysteresis, and three lines of protection for output overvoltage, overcurrent, and overtemperature.

Working Principle of LMR23630APDRRR

The LMR23630APDRRR regulator is a DC-DC converter based on a current-mode buck converter topology. It uses an external inductor to store energy and transfer it to the output when the power switch is on, and to the input when this switch is off. When the switch is on, the inductor stores energy by storing magnetic field and providing current to the output. When the switch is off, it releases the stored energy to the input through the diode, while providing current to the output. The switching frequency is programmed using an external resistor. The power flow is regulated by means of the topology\'s control loop, and the output voltage is adjusted using an external reference voltage and an error amplifier.

The current-mode control is the most commonly used control method for DC-DC converters because it offers good stability, fast transient response, and good efficiency. The LMR23630APDRRR is therefore ideal for applications where fast, low output voltage transient response is required.
