Figure 5 shows the critical power components of the converter.
To minimize the voltage overshoot the interconnecting wires
indicated by heavy lines should be part of ground or power
plane in a printed circuit board. The components shown in
Figure 5 should be located as close together as possible.
Please note that the capacitors C
IN
and C
O
each represent
numerous physical capacitors. Locate the HIP6004E within 3
inches of the MOSFETs, Q
1
and Q
2
. The circuit traces for the
MOSFETs’ gate and source connections from the HIP6004E
must be sized to handle up to 1A peak current.
Figure 6 shows the circuit traces that require additional
layout consideration. Use single point and ground plane
construction for the circuits shown. Minimize any leakage
current paths on the SS pin and locate the capacitor, C
SS
close to the SS pin because the internal current source is
only 10
μ
A. Provide local V
CC
decoupling between VCC and
GND pins. Locate the capacitor, C
BOOT
as close as practical
to the BOOT and PHASE pins.
Feedback Compensation
Figure 7 highlights the voltage-mode control loop for a
synchronous-rectified buck converter. The output voltage
(V
OUT
) is regulated to the Reference voltage level. The
error amplifier (Error Amp) output (V
E/A
) is compared with
the oscillator (OSC) triangular wave to provide a pulse-
width modulated (PWM) wave with an amplitude of V
IN
at
the PHASE node.
