The CINCON CHB300-300S, CFB600-300S and CFB750-300S are isolated brick DC-DC converter families designed for high-voltage DC power systems. They provide 300W, 600W and 750W output power respectively, with up to 3000VAC input-to-output isolation.

The main selection factors are required power, minimum input voltage, output voltage, brick size and thermal conditions.

Quick Comparison

CHB300-300S: Compact 300W Half-Brick Solution

The CHB300-300S is the smallest of the three families. Its industrial-standard half-brick package is useful when PCB space is limited and the load requires no more than 300W.

Available configurations include:

CFB600-300S: 600W with a 180–425VDC Input

The CFB600-300S doubles the available output power to 600W while retaining the same 180–425VDC input range as the CHB300-300S.

Its standard full-brick package provides three output choices:

CFB750-300S: Maximum Power and More Output Options

The CFB750-300S provides up to 750W in the same full-brick footprint as the CFB600-300S. It also offers the widest output selection, including 15V, 28V and 36V versions.

Which CINCON Converter Should You Choose?

Choose the CHB300-300S when:

• The required power is 300W or less.

• A compact half-brick footprint is preferred.

• A 5V output is required.

• The input bus may fall to 180VDC.

Choose the CFB600-300S when:

• The load requires up to 600W.

• The system needs a 180–425VDC input range.

• A 12V, 24V or 48V output is sufficient.

• Operation up to a +100°C case temperature is required.

Choose the CFB750-300S when:

• The system requires the highest available power.

• A 15V, 28V or 36V output is needed.

• The input bus remains above 200VDC.

• The thermal design can maintain the module within its specified case-temperature range.

FAQ

Are the three converter families pin-compatible?

No. The CHB300-300S uses a half-brick package, while the CFB600-300S and CFB750-300S use full-brick packages. PCB layout, pinout and thermal design must be checked separately.

Which models accept input voltages down to 180VDC?

The CHB300-300S and CFB600-300S operate from 180–425VDC. The CFB750-300S requires 200–425VDC.

Which series offers a 5V output?

Only the CHB300-300S family provides a 5V option, rated for up to 60A.

Do all three series provide 3000VAC isolation?

Yes. CINCON specifies 3000VAC input-to-output isolation for all three families.

Can the CFB600-300S be replaced directly by the CFB750-300S?

Not automatically. Although both use full-brick dimensions, their minimum input voltage, available outputs, current ratings, pin configuration and thermal limits must be verified before replacement.
