Description A Product Line of Diodes Incorporated AP3436/A 3A, 1.25MHz High Performance Synchronous Buck Converter Pin Assignments The AP3436/A is a step-down DC-DC converter with integrated power stage capable of driving up to 3A continuous output current. It integrates 2 N-channel power MOSFETs with low on-resistance. Current mode control provides fast transient response and cycle-bycycle current limit. For AP3436, the regulator adopts current-mode in forced pulse-width modulation (PWM) mode with 1.25MHz switching frequency internally, which allows small-sized components, such as capacitors and inductors. This feature greatly simplifies the design of switchmode power supplies. Under PWM mode, the device remains at the fixed PWM operation (typical at 1.
