STEVAL-ISB001V1 Cell phone battery charger demonstration board based on the STD1LNK60Z-1 Data brief Features ■ Vac = 85 to 265 V ■ Output voltage: 4.7 V ■ Output power: 1.9 W ■ RoHS compliant Description The STEVAL-ISB001V1 demonstration board is a ringing choke converter (RCC)-based, step-bystep cell phone battery charger. The RCC is essential to the self-oscillating flyback converter, and operates within the discontinuous conduction mode (DCM) and continuous conduction mode (CCM) boundaries without noticeable reverse recovery of the output rectifying diodes. STEVAL-ISB001V1 RCC control is achieved by using discrete components to control the peak current mode, so the overall RCC cost is relatively low compared to the conventional pulse width modulation (PWM) IC flyback converter. As a result, RCC is widely used for low-power applications in industry and home appliances as a simple and cost-effective solution.
