3 Description
TPIC2030 is very-low noise type motor driver IC
suitable for slim or ultra-slim DVD reader/writer. The
integrated current sense resistance for the spindle
motor reduces cost and board area in designs. The
TPIC2030 is an integrated solution for driving the
spindle motor, sled motor, load motor, and Focus /
Tracking / Tilt actuators in an optical disk drive. It also
integrates a synchronous DC-DC converter to supply
1.0 or 3.3 V. The discontinuous mode regulation
feature on the DC-DC converter improves efficiency
at low power consumption.
