FIX-LC5-1 is an integrated circuit (IC) designed to handle multiple-channel low-current power supply control. It includes two voltage control oscillators (VCOs) specifically configured for low-current applications such as small primary side applications, LED lighting, and small consumer applications. The VCOs are also particularly suitable for AC/DC converters, which can provide both charging and digital control. FIX-LC5-1 is programmed on customizable Digital Control Registers (DCRs), before providing a reliable digital interface for system control and information. Additionally, the IC comes with an extra sleep mode for system power down mode and standby phase operations.
