AP63201WU-7 is a high-performance synchronous step-down DC-DC converter from Diodes Incorporated, designed for communication, industrial, consumer, and automotive power supplies. It supports an input voltage range of 4.5V to 24V and delivers continuous load current up to 2A.
Integrated low on-resistance power MOSFETs with constant on-time control architecture provide fast transient response, low output voltage ripple, and reduced peripheral components for high-efficiency point-of-load voltage conversion.
Auto-switching PWM/PFM mode optimizes efficiency: PFM improves light-load efficiency while PWM maintains stable output ripple during heavy load operation.
Internal soft-start function limits inrush current during power-on, prevents front-end power rail voltage drop, and supports orderly power supply sequencing for multiple chips.
Integrated undervoltage lockout (UVLO), cycle-by-cycle overcurrent limiting, and thermal shutdown protection safeguard the chip and downstream circuits from damage.
Compact SOT-23-6 surface mount package, lead-free and halogen-free, fully RoHS compliant, ideal for space-constrained PCB layouts.
