The device offers selectable switching frequencies of 400kHz or 2.2MHz, allowing designers to optimize for either efficiency or solution size. With 25\u00b5A quiescent current and integrated 85m\u03a9\/55m\u03a9 MOSFETs, it achieves up to 92% efficiency while maintaining excellent light-load performance.","working_principle":"The LMR23630AFDDA uses peak current mode control with a fixed-frequency oscillator. The error amplifier compares a fraction of the output voltage with the internal reference, generating a control voltage that sets the peak inductor current. The high-side N-channel MOSFET is turned on at the clock edge and turned off when the peak current threshold is reached, while the low-side MOSFET conducts during the off-time. In light-load conditions, the device enters PFM mode, skipping pulses to reduce switching losses and maintain high efficiency. The integrated slope compensation prevents sub-harmonic oscillation at duty cycles above 50%.","pin_description":"
