Working Principle

The LMR23630FQDRRRQ1 operates by switching on and off of an internal power transistor. This power switch is controlled by an internal control circuitry that operates in either pulse width modulation (PWM) or pulse frequency modulation (PFM) mode. In PWM mode, the speed of the internal power switch is varied in synchronization with an external clock signal. This provides a more stable and efficient output voltage, however it may come with added complexity and system cost. In PFM mode, the control circuitry monitors the voltage drop across the output and adjusts the power switch frequency based on this voltage measurement. This provides a simpler system design at the cost of lower maximum operating frequency. The LMR23630FQDRRRQ1 also features several additional features such as dynamic voltage scaling, programmable output voltage, and under voltage lockout and operation in sleep mode.
