NCV887601BSTGEVB NCV887601 Automotive Grade High-Frequency Start-Stop Boost Controller Evaluation Board User'sManual http://onsemi.com EVAL BOARD USER’S MANUAL Description Key Features • • • • • • This NCV887601 evaluation board provides a convenient way to evaluate a high frequency boost controller designed to supply a minimum output voltage during Start-Stop vehicle battery voltage sags. The unit is in low Iq sleep-mode under normal battery operating condition and will wake-up when the monitored voltage drops below 7.3 V and begin regulating once 6.8 V is reached. Switching frequency is set to 440 kHz with a user selectable ROSC resistor. The evaluation board is rated 6.8 V / 3.6 A at a 2.6 V input voltage. Operation below 2.6 V is possible if output current is reduced. • • • Automatic enable below 7.3 V Boost Operation at 6.8 V 440 kHz Switching Frequency Input Undervoltage Lockout Wide Input Voltage of 2.6 V to 45 V Low Quiescent Current in Sleep Mode (
