Parameter Condition Min Typ Max Units Supply Voltage Range 2.3 5.5 V EN = VIN; VFB = 0.55V (not switching) 350 450 µA Quiescent Current EN = 0V 0.01 1 µA MIC2202 [Adjustable] Feedback Voltage 0.4875 0.5 0.5125 V Output Voltage Line Regulation VOUT < 2V; VIN = 2.3V to 5.5V, ILOAD= 100mA 0.05 0.5 % Output Voltage Load Regulation 0mA < ILOAD < 500mA 0.1 0.5 % Bias Regulator Output Voltage 2.2 2.32 2.6 V Maximum Duty Cycle VFB = 0.7V 100 % Current Limit VFB = 0.7V 1 1.8 2.5 A Switch ON-Resistance VIN = 3.5V, ISW = 300mA; VFB = 0.35V 0.65 0.9 Ω VIN = 3.5V, ISW = 300mA; VFB = 0.55V 0.55 0.75 Ω Enable Input Current 0.01 1 µA Sync Frequency Range 1.6 2.5 MHz SYNC_IN Threshold 0.7 1 1.7 V Sync Minimum Pulse Width 10 ns SYNC_IN Input Current 1 µA Oscillator Frequency 1.8 2 2.2 MHz Enable Threshold 0.5 0.9 1.3 V Enable Hysteresis 20 mV Over-temperature Shutdown 160 °C Over-temperature Shutdown Hysteresis 20 °C Notes: 1. Exceeding the absolute maximum rating may damage the device. 2. The device is not guaranteed to function outside its operating rating. 3. Absolute maximum power dissipation is limited by maximum junction temperature where PD(MAX) = (TJ(MAX) – TA) ÷ θJA. 4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF. 5. Specification for packaged product only. |
