The RZC2125 provides accurate constant
voltage, constant current (CV/ CC) regulation
without requiring an opto-coupler and the
secondary control circuitry. It also eliminates
the need of loop compensation circuitry while
maintaining good stability. The RZC2125 can
achieve excellent regulation and high average
efficiency, yet meets no-load consumption less
than 100mW. It can also achieve excellent
dynamic performance.
