AN6559/B are monolithic step-down switch mode converters with a built-in high-side power MOSFET and a gate driver for a low side external power MOSFET. They achieve 6A/8A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. The converter can be configured as single output or dual outputs with independent over current protection (OCP). Fault condition protections include cycle-by-cycle current limit and thermal shutdown. AN6559/B are available in TSSOP14-EP packages, provide very compact system solution and good thermal conductance.
