High Efficiency 1MHz, 2A Step Up Regulator
DATASHEET
TD8228
General Description
Features
TD8228 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
Adjustable Over Current Protection:0.5~4.5A
RoHS Compliant and Halogen Free
Compact package: SOT23-6
Applications
Cell Phone and Smart Phone
PDA, PMP, MP3
Digital Camera
Package Types
