The onsemi CAT3643HV2-GT2 is a 3-output DC-DC regulator IC featuring a switched capacitor (charge pump) topology. This device is engineered for efficient LED driving applications, specifically in backlighting. It supports multi-step dimming for precise light control. Each of the three outputs can deliver up to 32mA of current. The internal switch design simplifies implementation, and the device operates with a switching frequency ranging from 1MHz to 1.3MHz. The CAT3643HV2-GT2 is supplied in a compact 12-TDFN (3x3) package with an exposed pad for enhanced thermal performance, suitable for surface mount assembly. Its operating temperature range is -40°C to 85°C. The input voltage range is 2.5V to 5.5V, with an output voltage capability of up to 7V. This component is commonly found in display backlighting solutions.
