SC451
Portable IMVP-IV™ and IMVP-IV+™
Single Phase Power Supply Controller
POWER MANAGEMENT
Description
Features
The SC451 PowerStep IV™ IC is a single chip high-perfor-
mance Hysteretic PWM controller. With its integrated
SmartDriver™, it powers advanced IMVP-IV™ and IMVP4+™
processors. The SC451 features extended Intel Mobile Volt-
age Positioning (IMVP™) to increase battery life by reduc-
ing the voltage at the processor when it is heavily loaded.
It directly supports Intel’s SpeedStep® processors for even
longer battery life. The SC451 fully supports the Intel®
Geyserville-III core voltage specification. It provides direct
“deeper sleep” mode and boot voltage support. Automatic
“power-save” is present to prevent negative current flow in
the low-side FET during light loading conditions, saving even
more power. The high side driver initially turns on with a
IMVP-IV™ and IMVP-IV+™ compliant single chip
solution
On chip CLK_ENABLE# and IMVP4_PWRGD outputs
Backward compatible with SC1479
High speed hysteretic controller
Single phase operation
Selectable analog or VID controlled DeeperSleep
setting
6 bit VID programmable output
Integrated drivers with soft high side turn-on
Programmable softstart
Programmable boot voltage
weak drive to reduce ringing, EMI, and capacitive turn-on Programmable DeeperSleep voltage
of the low side.
Under-voltage lock out on VccA
Over-voltage protection on CORE
A 6-bit DAC, accurate to 0.85%, sets the output voltage Current limit protection on CORE

Applications
DataShee
The SC451 operates from 5Vdc and also features soft-start, Low power Notebook and Laptop computers
an open-drain PWRGD signal with power-good blanking, Embedded Applications
and an enable input. Programmable current limiting shuts
down the SC451 after 32 current limit pulses. In addition,
it comes in a space-saving MLP 6X6-28 and TSSOP-28
package. TSSOP-38 package is also available which pro-
vides a pin to pin upgrade to a dual phase solution using
Semtech’s dual phase controller SC450.
