Frequently Asked Questions

What topologies are supported by CR Micro power management ICs?

CR Micro power management ICs support a wide range of topologies: (1) AC-DC: Flyback, forward, and buck for offline power supplies. (2) DC-DC: Buck (step-down), boost (step-up), and buck-boost for battery-powered and intermediate bus applications. (3) LED drivers: Buck, boost, buck-boost, and flyback for various LED lighting configurations. (4) Battery management: Linear and switching chargers, protection ICs, and fuel gauges. Each topology is optimized for specific application requirements such as input voltage range, output power, efficiency targets, and cost constraints.

Contact our FAE team for topology selection guidance based on your specific application requirements.

What protection features are included in CR Micro power management ICs?

CR Micro power management ICs include comprehensive protection features: (1) Over-current protection (OCP) - cycle-by-cycle current limiting and hiccup mode. (2) Over-voltage protection (OVP) - latches off or auto-restart on output overvoltage. (3) Over-temperature protection (OTP) - shuts down at excessive junction temperature with hysteresis. (4) Under-voltage lockout (UVLO) - disables operation at insufficient input voltage. (5) Short-circuit protection (SCP) - current limiting during output short. (6) Open-LED protection for LED drivers. These protections ensure safe and reliable operation under abnormal conditions.

Contact our FAE team for detailed protection feature specifications and application-specific recommendations.

Do CR Micro LED drivers support dimming functions?

Yes, CR Micro LED drivers support various dimming methods: (1) Analog dimming - adjust LED current by changing the control voltage or resistor. (2) PWM dimming - pulse-width modulation for high-contrast ratio dimming (up to 1000:1). (3) Triac/phase-cut dimming - compatible with standard wall dimmers for retrofit applications. (4) Digital dimming - I2C or 1-wire interface for smart lighting control. The specific dimming options depend on the LED driver model. CR Micro provides reference designs and application notes for implementing different dimming methods.
