AP68255Q/AP68355Q 5.5V TO 80V INPUT AUTOMOTIVE GRADE, 2.5A AND 3.5A STANDARD BUCK CONVERTER Description Pin Assignments
The AP68255Q/AP68355Q is an internally compensated, standard DC-DC buck converter with a default frequency of 300kHz. The device GND 1 8 SW fully integrates a 500mΩ high-side power MOSFET power MOSFET to provide highly efficient step-down DC-DC conversion. The AP68255Q/AP68355Q device is easily used by minimizing the VIN 2 7 BST external component count due to its adoption of Constant On-Time EPAD (COT) control to achieve fast transient response, easy loop 9 stabilization, and low output voltage ripple. EN 3 6 NC The AP68255Q/AP68355Q design is optimized for Electromagnetic Interference (EMI) reduction. The device has a proprietary gate driver NC 4 5 FB scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high frequency radiated EMI noise caused by MOSFET switching.
SO-8EP
The AP68255Q/AP68355Q is available in the standard Green SO-8EP package.
