Switch on time is limited by an internal 30 μs (typical)
timer, minimizing stress to the power components.
Programmable Output
The CS5166 is designed to provide two methods for
programming the output voltage of the power supply. A five
bit on board digital to analog converter (DAC) is used to
program the output voltage within two different ranges. The
first range is 2.125 V to 3.525 V in 100 mV steps, the second
is 1.325 V to 2.075 V in 50 mV steps, depending on the
digital input code. If all five bits are left open, the CS5166
enters adjust mode. In adjust mode, the designer can choose
any output voltage by using resistor divider feedback to the
VFB pin, as in traditional controllers. The CS5166 is
specifically designed to meet or exceed Intel’s Pentium II
specifications.
Start Up
Until the voltage on the VCC supply pin exceeds the 3.95 V
monitor threshold, the Soft Start and GATE pins are held
low. The FAULT latch is reset (no Fault condition). The
output of the error amplifier (COMP) is pulled up to 1.0 V by
the comparator clamp. When the VCC pin exceeds the
monitor threshold, the GATE(H) output is activated, and the
Soft Start capacitor begins charging. The GATE(H) output
will remain on, enabling the NFET switch, until terminated
by either the PWM comparator, or the maximum on time
timer.
If the maximum on time is exceeded before the regulator
output voltage achieves the 1.0 V level, the pulse is
terminated. The GATE(H) pin drives low, and the GATE(L)
pin drives high for the duration of the extended off time. This
time is set by the time out timer and is approximately equal
to the maximum on time, resulting in a 50% duty cycle. The
GATE(L) pin will then drive low, the GATE(H) pin will
drive high, and the cycle repeats.
When regulator output voltage achieves the 1.0 V level
present at the COMP pin, regulation has been achieved and
normal off time will ensue. The PWM comparator
terminates the switch on time, with off time set by the COFF
capacitor. The V2 control loop will adjust switch duty cycle
as required to ensure the regulator output voltage tracks the
output of the error amplifier.
The Soft Start and COMP capacitors will charge to their
final levels, providing a controlled turn on of the regulator
output. Regulator turn on time is determined by the COMP
capacitor charging to its final value. Its voltage is limited by
the Soft Start COMP clamp and the voltage on the Soft Start
pin.
