What Are HCW Through-Hole (DIP) Power ICs?
This IC family includes several models—HC2705HD, HC9605B, HC9605F, among others—packaged in the classic Dual Inline Package (DIP), designed for ease of prototyping and compatibility with breadboards and through-hole PCB layouts

. These components are tailored for AC-to-DC conversion, finding everyday applications in mobile chargers, LED drivers, and low-power adapters.

Notable Models & Their Specifications
Although details for every DIP model aren't fully listed on the site, we can draw insights by referencing similar HCW SMD ICs that share design paradigms:

HC2702B (SMD, 5W)
Provides stable 5 V output at up to 1.2 A.

Operates across a wide AC input range (100–264 V).

Includes short circuit, overload, and over-temperature protections.

Performs regulation via primary-side control—eliminating the need for opto-couplers ...
... and secondary feedback circuits

HC2702F (SMD, 12W)
Delivers up to 12 W power output, ideal for more demanding chargers.

Has built-in functionalities, such as internal BJT power switch, output cable-compensation, and a blend of PFM (Pulse Frequency Modulation) and PWM (Pulse Width Modulation) control for tight voltage/current regulation.

Provides robust protection: overload, short-circuit, VCC undervoltage, and over-temperature

By analogy, the Through-Hole variants are likely to offer similar electrical features—primary-side regulation, efficient conversion, and comprehensive protection—while delivering the mechanical benefits of DIP packaging.

Advantages of Through-Hole (DIP) Format
Ease of Prototyping & Repair
DIP ICs are ideal for breadboards and socketed designs, making them perfect for rapid prototyping or repair-friendly applications.

Thermal Performance
The larger physical footprint of DIP packages can better dissipate heat compared to SMD variants—especially useful in continuous-load scenarios.

Mechanical Stability
Through-hole mounting offers stronger solder joints, enduring vibration or mechanical stress—vital in rugged or industrial environments.

Compatibility
Circuit designers and hobbyists often favor DIP parts due to their broad support across development platforms and tools.

Applications That Shine
Given the AC-to-DC converter nature of these HCW DIP ICs, their applications are varied and valuable:

Mobile and Small-Device Chargers: Reliable 5 V outputs make them ideal for powering phones, wearables, and IoT accessories.

LED Power Supplies: Provide compact, safe voltage regulation for LEDs in both consumer and industrial lighting.

Low-Power Adapters: Useful in scenarios where space is tight but reliability is essential—powering sensors, mini-controllers, or embedded devices.

Design Considerations & Best Practices
To fully harness these ICs:

Check Thermal Ratings
Ensure your design includes adequate heat dissipation—even with DIP’s thermal advantages.

Match Input Range Carefully
Confirm compatibility with your AC source (e.g., 100–264 V)—essential for universal charger designs.

Build in Protections
Many HCW ICs include built-in protections—but always cross-check if supplementary components (e.g., fuses or inrush limiters) are needed.

Simplify Circuitry
Take advantage of the primary-side regulation to eliminate opto-couplers, reducing parts count and PCB complexity.

Understand Power Limitations
Stick within specified power ratings—like 5 W for HC2702B or 12 W for HC2702F-class devices. Overshoot can stress the chip and compromise longevity.

Final Thoughts
The HCW Through-Hole (DIP) Power IC series bridges heritage packaging with modern efficiency and protections—perfect for makers, educators, and commercial developers alike. Whether designing cost-effective mobile chargers, LED drivers, or compact power adapters, these ICs deliver simplicity, safety, and performance—all without complex peripheral circuitry.
