Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX16929 is a highly integrated power supply for
automotive TFT-LCD applications. The device integrates
one buck converter, one boost converter, one 1.8V/3.3V
regulator controller, and two gate voltage regulators.
The device comes in several versions to satisfy com-
mon automotive power-supply requirements (see the
Ordering Information/Selector Guide
Designed to operate from a single 4V to 28V supply or
5.5V to 28V supply, the device is ideal for automotive
TFT-LCD applications.
Both the buck and boost converters use spread-spec-
trum modulation to reduce peak interference and to opti-
mize EMI performance.
The sequencing input (SEQ) allows flexible sequencing
of the positive-gate and negative-gate voltage regulators.
The power-good indicator (PGOOD) indicates a failure
on any of the converters or regulator outputs. Integrated
thermal shutdown circuitry protects the device from over-
heating.
The MAX16929 is available in a 28-pin TSSOP pack-
age with exposed pad, and operates over the -40NC to
+105NC temperature range.
