Features

Description

The DFC10 Series provides power converter solutions to

meet commercial and industrial requirements. With power

densities above 11 watts per cubic inch (0.67 watts per

• RoHS lead-solder-exemption compliant

• High power density, up to 11 watts per cubic inch

(0.67 watts per cm )

cm ), overcurrent protection, and five-sided shielded

• Efficiencies to 83% (Lower for 3.3V)

• Low input-to-output capacitance

• 700V isolation (1544V for 48V converters)

• Continuous overcurrent protection

• 3.3V output available

case, the DFC10 meets the most rigorous needs in an

industry-standard case size. The 220 kHz operating

frequency of the DFC10 Series allows an increased power

density while including adequate heat sinking and

input/output filtering. This eliminates the need for external

components in most applications. Full overload protection

is provided by pulse-by-pulse current limiting.

• 5-Sided, shielded copper case

• Extended input range (2:1)

NOTES

(1) All parameters measured at Tc = 25°C, nominal input voltage and

full rated load unless otherwise noted.

(2) The Case is tied to the -Input pin.

(3) The functional temperature range is intended to give an additional

data point for use in evaluating this power supply. At the low functional

temperature the power supply will function with no side effects,

however, sustained operation at the high functional temperature will

reduce expected operational life. The data sheet specifications are

not guaranteed beyond the case operating range.

(4) The case thermal impedance is specified as the case temperature

rise over ambient per package watt dissipated.

NOTES

capacitor may be required at the input pins for proper operation.

This input capacitor should have an ESR greater than 0.25

ohms. Input capacitors with an ESR less than 0.25 ohms may

cause peaking of the input filter and actually degrade circuit

performance.

External output capacitance is not required for operation.

However, it is recommended that 1 μF to 10 μF of tantalum and

0.001 to 0.1 μF ceramic capacitance be selected for reduced

system noise. Additional output capacitance may be added for

increased filtering, but should not exceed 400 μF.

(1) All parameters measured at Tc = 25°C, nominal input voltage and full

rated load unless otherwise noted.

(2) Noise measurement bandwidth is 0-20 MHz for peak-peak

measurements, 10 kHz to 1 MHz for RMS measurements. Output noise is

measured with a 0.01μF / 100V ceramic capacitor in parallel with a 1μf / 35V

Tantalum capacitor, 1 inch from the output pins to simulate standard PCB

decoupling capacitance.

(3) Short term stability is specified after a 30 minute warmup at full load,

constant line and recording the drift over a 24 hour period.

(4) The input ripple rejection is specified for DC to 120 Hz ripple with a

modulation amplitude of 1% of Vin.

Negative Outputs:

A negative output voltage may be obtained by connecting the

+OUT to circuit ground and connecting -OUT as the negative

output.

DFC10 SERIES APPLICATION NOTES

External Capacitance Requirements:

No external capacitance is required for operation of the DFC10 Series. If a

capacitive input source is farther than 1” from the converter, an additional
