Frequently Asked Questions

How do I select between TC1508 and TC1509?

Choose TC1508 for applications requiring up to 2A output current with cost-sensitive requirements. Select TC1509 for higher current needs up to 3A, especially for industrial applications requiring integrated switches and power-good output. Both offer similar input voltage range and efficiency.

TC1508 for 2A consumer applications; TC1509 for 3A industrial applications requiring higher performance features.

What is the efficiency of Superchip DC-DC converters?

Superchip DC-DC converters achieve peak efficiency of 93-94% depending on the model. Efficiency is maintained above 85% across wide load range thanks to synchronous rectification. Actual efficiency depends on input voltage, output voltage, and load current.

Expect 85-94% efficiency depending on operating conditions; calculate power dissipation for thermal design.

Are Superchip DC-DC converters suitable for automotive applications?

Superchip offers industrial-grade DC-DC converters qualified for -40°C to +85°C temperature range. While not specifically AEC-Q100 qualified, many products are used in non-safety-critical automotive applications. For safety-critical applications, verify specific qualifications or consider automotive-grade alternatives.

Suitable for non-safety-critical automotive; verify qualifications for specific applications or contact FAE for recommendations.

What is the switching frequency of Superchip converters?

Superchip DC-DC converters operate at fixed switching frequencies ranging from 1.2MHz to 1.5MHz depending on the model. This high switching frequency enables the use of small external inductors and capacitors, reducing solution size and cost.

High frequency enables compact designs; verify EMI requirements are met with proper layout and filtering.

Do Superchip converters require external compensation?

Most Superchip DC-DC converters feature internal compensation, eliminating the need for external compensation components. This simplifies design and reduces external component count. The internal compensation is optimized for typical applications with ceramic output capacitors.

Internal compensation simplifies design; follow datasheet recommendations for output capacitor selection for stable operation.
