General Description
Features
TD8208 is a high efficiency, current-mode control Boost DC to DC
regulator with an integrated 120mΩ RDS(ON) N-channel MOSFET. The fixed 1MHz switching frequency and internal compensation reduce external component count and save the PCB space. The build-in internal soft start circuitry minimizes the inrush current at start-up.
Wide input range:2.5-6V 1MHz switching frequency Minimum on time: 100ns typical Minimum off time: 100ns typical Max output voltage: 6V Low RDS(0N): 120mΩ RoHS Compliant and Halogen Free Compact package: SOT23-6
Applications
Cell Phone and Smart Phone PDA, PMP, MP3 Digital Camera
