... Pulse by pulse current limiting is implemented by sensing the differential voltage across an external resistor appropriately sized PC board trace. The SC1101 operates at a fixed frequency of 200kHz, providing an optimum compromise between efficiency, external component size, and cost. Typical Application Circuit ...

... Capacitor(s) and the Cin, Q1, D1 loop. Under no circum- stances should GND be returned to a ground inside the Cin, Q1, D1 loop. 6) Vcc for the SC1101 should be supplied from the 5V supply through a 10 resistor, the Vcc pin should be decoupled directly to GND by a 0.1µF ceramic capacitor, trace lengths should be as short as possible ...
