Unlike the PFM-mode AP62200WU, this variant maintains constant switching frequency at all loads for minimal output voltage ripple\u2014critical for noise-sensitive RF, audio, and DAC power rails. It features integrated 90m\u03a9\/65m\u03a9 MOSFETs, COT control, proprietary EMI-optimized gate driver, and 2.5ms internal soft-start. Pin-compatible with AP62200WU in TSOT-26 package.","working_principle":"The AP62201WU-7 operates using constant-on-time (COT) control in forced continuous conduction mode (FCCM). Unlike PFM mode where the device skips pulses at light loads, FCCM forces the low-side MOSFET to conduct even during negative inductor current, maintaining constant switching frequency. This eliminates the variable frequency noise that can interfere with sensitive analog circuits. The proprietary gate driver scheme shapes the MOSFET switching edges to reduce high-frequency ringing on the SW node, minimizing radiated EMI. The on-time is adaptively calculated based on VIN\/VOUT to maintain approximately 750kHz switching frequency. The valley current limit monitors the low-side current on a cycle-by-cycle basis for overcurrent protection.","pin_description":"
