TPS40140
DUAL OR 2-PHASE, STACKABLE CONTROLLER
SLUS660A – SEPTEMBER 2005 – REVISED JULY 2006
• VDD From 4.5 V to 15 V, With Internal 5-V
Regulator
• V
OUT From 0.7 V to 5.8 V
• Converts From 15V Input to 0.7V Output at
1MHz
• Dual-Output or 2-Phase Interleaved Operation,
Stackable to 16 Phases
• Supports Pre-Biased Outputs
Programmable Switching Frequency Up to 1
MHz/Phase
• 0.5% Internally Trimmed 0.7-V Reference
• 10-µA Shutdown Current
• Current Mode Control with Forced Current
Sharing(1)
• 1V to 40V Power Stage Operation Range
• Power Sharing from Different Input Voltage
Rails, (e.g. Master From 5 V, Slave From 12 V)
• True Remote Sensing Differential Amplifier
• Programmable Input Undervoltage Lockout
The
TPS40140
is
a
multifunctional
synchronous
buck
controller
that
can
be
• Resistive or Inductor DCR Current Sensing
configured to provide either a single-output
• Provide a 6-Bit Digitally-Controlled Output
two-phase power supply or a power supply
When Used With TPS40120
that
supports
two
independent
outputs.
• 36-pin QFN Package
Several TPS40140 controllers can be stacked
up to a 16-phase multiphase single output
power supply. Alternatively, several controllers
providing multiple independent outputs can be
• Graphic Cards
synchronized in an interleaving pattern for
• Internet Servers
improved input ripple current.
• Networking Equipment
The TPS40140 is capable of converting from a
• Telecommunications Equipment
15-V input to a 0.7-V output at 1MHz.
• DC Power Distributed Systems
Each phase operates at a switching frequency
of up to 1 MHz. The two phases in one device
operate 180
° out-of-phase. In a multiple device
stackable configuration, the phase shift of the
