Adjustable output from 1.2V to 37V via external resistor divider. 150kHz switching frequency for small inductor. Up to 90% efficiency. Internal 2A\/60V NPN switch with current-mode control.","working_principle":"Current-mode PWM controller drives an internal 2A NPN power switch. During switch on-time, current builds in the external inductor. During off-time, inductor current flows through the external catch diode to the load and output capacitor. Output: Vout = 1.23V * (1 + R2\/R1). Current-mode control provides cycle-by-cycle current limiting and fast transient response. Soft-start limits inrush current during startup.","pin_description":"
