Capacitor Type Group by ESR (Equivalent Series Resistance)
Type A = (100<capacitance×ESR≤1,000)
Type B = (1,000<capacitance×ESR≤5,000)
Type C = (5,000<capacitance×ESR≤10,000)
Input And Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the DC/DC regulator. It is
important that the input source has low characteristic
impedance. The regulators are designed for stable
operation without external capacitors connected to the
input or output. The performance in some applications can
be enhanced by addition of external capacitance as
described under External Decoupling Capacitors. If the input
voltage source contains significant inductance, the addition
of a 100 F capacitor across the input of the regulator will
ensure stable operation. The capacitor is not required when
powering the DC/DC regulator from an input source with an
inductance below
10 H.
External Decoupling Capacitors
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load
can be improved by addition of decoupling capacitors at
the load.
The most effective technique is to locate low ESR ceramic
and electrolytic capacitors as close to the load as possible,
using several parallel capacitors to lower the effective ESR.
The ceramic capacitors will handle high-frequency dynamic
load changes while the electrolytic capacitors are used to
handle low frequency dynamic load changes. Ceramic
capacitors will also reduce any high frequency noise at the
load.
It is equally important to use low resistance and low
inductance PCB layouts and cabling.
External decoupling capacitors will become part of the
control loop of the DC/DC regulator and may affect the
stability margins. As a “rule of thumb”, 100 F/A of output
current can be added without any additional analysis. The
ESR of the capacitors is a very important parameter. Power
Modules guarantee stable operation with a verified ESR
value of >10 m across the output connections.

Power Modules representative.
Output Voltage Adjust (V
adj)
The DC/DC regulators have an Output Voltage Adjust pin
(Vadj). This pin can be used to adjust the output voltage
above or below Output voltage initial setting.
To increase or decrease the voltage, the resistor should be
connected between the Vadj pin and GND pin. The resistor
value of the output voltage adjust function is according to
information given under the output section for the
respective product.
Parallel Operation
Two regulators may be paralleled for redundancy if the total
power is equal or less than PO max. It is not recommended
