It uses current-mode PWM control with an internal 1A N-channel MOSFET. The 1.25V feedback reference sets the output voltage via external resistor divider: VOUT = 1.25V x (1 + R1\/R2). The SHDN pin (active HIGH, unusual) enables the device when driven above 1.3V, with an internal pull-down ensuring the device is off when the pin is floating. The 600kHz switching frequency balances efficiency and inductor size: a 10uH inductor is typical for 5V-to-12V boost at 200mA load. The current-mode architecture provides inherent cycle-by-cycle current limiting and stable operation with ceramic output capacitors. Peak efficiency reaches 90% at moderate load currents. The device supports output voltages up to 40V, suitable for OLED bias, LCD bias, and SEPIC converter applications. The NOPB suffix indicates lead-free (Pb-free) manufacturing. Soft-start is not internally provided; an external capacitor on the FB node can be used for controlled start-up.","pin_description":"
