DESCRIPTION
The SC1406A is a High Speed, High performance
Hysteretic Mode controller. It is part of a two chip solu-
tion, with the SC1405 Smart Driver, providing power
to advanced micro-processors. It uses a Dynamic Set
Point switching technique along with an ultra-fast com-
parator to provide the control signal to an external
high speed Mosfet driver. A 5-bit DAC sets the output
voltage, thus providing a voltage resolution of 25mV.
SC1406A has two on-chip linear regulators which
drive external PNP transistors with output voltage set-
tings of 1.5V and 2.5Vdc. The linear regulator drivers
have a separate soft start. A PWRGD TTL level signal
is asserted when all voltages are within specifications.
The part features Low Battery Detect and Undervolt-
age Lock-Out for the main Hysteretic controller to as-
sure V-DC is within acceptable limits. An Over-Current
comparator disables the main controller during an
overcurrent condition using an externally pro-
grammable threshold.
FEATURES
High Speed Hysteretic controller provides high
efficiency over a wide operating load range
