12V 스텝업 전압 레귤레이터 U3V40F12
(12V Step-Up Voltage Regulator U3V40F12)
개요
- 본 제품은 12V 스텝업 전압 레귤레이터 U3V40F12 입니다.
- 1.3V -12V 전압을 입력 받아 12V로 출력하여 주는 제품입니다.
특징
- Output voltage: 12 V with 4% accuracy
- Input voltage: 1.3 V to 12 V (Note: minimum start-up voltage is 2.7 V; see the connections section for details.)
- Typical efficiency of 85% to 95%, depending on input voltage, output voltage, and load (see the efficiency graph below)
- Switching frequency: ~600 kHz under heavy loads
- Power-save mode with ultrasonic operation that increases light load efficiency by reducing switching frequency, but keeps it above the audible range (20 kHz)
- Typical no-load quiescent currents under 2 mA (see the quiescent current graph below)
- 9.5 A switch allows for:
- Instantaneous input currents up to 9.5 A
- Input currents up to 4 A for several seconds
- Input currents up to 3.5 A for prolonged durations
- Integrated protections:
- Over-temperature shutdown
- Soft-start feature limits inrush current and gradually ramps output voltage
- Output over-voltage protection (typically at 16.5V)
- Cycle-by-cycle input current limiting to 9.5 A while boosting
- Compact size: 0.6″ × 0.6″ × 0.22″ (15.2 × 15.2 × 5.6 mm)
- Weight: 1.5 g
