DESCRIPTIO
FEATURES
The LT®3460 is a general purpose step-up DC/DC con-
verter. The LT3460 switches at 1.3MHz, allowing the use
of tiny, low cost and low height capacitors and inductors.
The constant frequency results in low, predictable output
noise that is easy to filter.

latch is reset turning off the power switch. The level at the
negative input of A2 is set by the error amplifier A1, and is
simply an amplified version of the difference between the
feedback voltage and the reference voltage of 1.255V. In
this manner, the error amplifier sets the correct peak
current level to keep the output in regulation. If the error
amplifier’s output increases, more current is delivered to
the output; if it decreases, less current is delivered.
The LT3460 uses a constant frequency, current mode
control scheme to provide excellent line and load regula-
tion. Operation can be best understood by referring to the
block diagram in Figure 1. At the start of each oscillator
cycle, the SR latch is set, which turns on the power switch
Q1. A voltage proportional to the switch current is added
to a stabilizing ramp and the resulting sum is fed into the
positive terminal of the PWM comparator A2. When this

Feedback Loop Compensation
is about 70kHz.
The LT3460 has an internal feedback compensation net-
work as shown in Figure 1 (RC and CC). However, because
thesmallsignalcharacteristicsofaboostconverterchange
with operation conditions, the internal compensation net-
work cannot satisfy all applications. A properly designed
external feed forward capacitor from VOUT to FB (CF in
Figure 2) will correct the loop compensation for most
applications.
The feedback loop gain T(s) = K3 • GP(s) • GC(s). If it
crosses over 0dB far before fZ, the phase margin will be
small. Figure 3 is the Bode plot of the feedback loop gain
measured from the converter shown in Figure 2 without
the feedforward capacitor CF. The result agrees with
the previous discussion: Phase margin of about 20° is
insufficient.

Figure 2. 5V to 12V Step-Up Converter
The LT3460 uses peak current mode control. The current
feedback makes the inductor very similar to a current
source in the medium frequency range. The power stage
transfer function in the medium frequency range can be
approximated as:
Figure 3
In order to improve the phase margin, a feed-forward
capacitor CF in Figure 2 can be used.
Without the feed-forward capacitor, the transfer function
from VOUT to FB is:
K1
s •C2

=
,
FB
R1
=
VOUT R1+R2
where C2 is the output capacitance, and K1 is a constant
based on the operating point of the converter. In continu-
ous current mode, K1 increases as the duty cycle de-
creases.
With the feed-forward capacitor CF, the transfer function
becomes:

margin, CF should be chosen so that the midpoint fre-
quency between the zero and the pole is at the cross over
frequency.
The feed-forward capacitor increases the gain at high
frequency. The feedback loop therefore needs to have
enoughattenuationattheswitchingfrequencytorejectthe
switching noise. Additional internal compensation com-
ponents have taken this into consideration.
With CF = 20pF, the feedback loop Bode plot is reshaped
as shown in Figure 4. The phase margin is about 60°.
For most of the applications of LT3460, the output capaci-
tor ESR zero is at very high frequency and can be ignored.
If a low frequency ESR zero exists, for example, when a
high-ESR Tantalum capacitor is used at the output, the
phasemarginmaybeenoughevenwithoutafeed-forward
capacitor.Inthesecases,thefeed-forwardcapacitorshould
not be added because it may cause the feedback loop to
not have enough attenuation at the switching frequency.
