It is designed for LED driver applications (white LED backlights) and boost power conversion. The control scheme is constant-off-time (COT) peak current mode: the MOSFET turns on and current ramps up through the inductor; when the peak current reaches the threshold set by the FB pin, the MOSFET turns off for a fixed 330ns (at VIN=5V), allowing the inductor current to flow through the diode to the output. The 1.5MHz switching frequency allows the use of small 2.2-4.7uH inductors in 0805 footprint and 1uF ceramic output capacitors. For LED driver applications, a sense resistor (RSET) from FB to GND sets the LED current: ILED = 0.25V \/ RSET (e.g., RSET=8.3 ohm for 20mA). The output voltage is self-regulating: the boost converter raises VOUT until the desired LED current flows through RSET, producing 0.25V at FB. For standard boost applications, a resistor divider from VOUT to FB sets the output voltage: VOUT = 0.25V x (1 + R1\/R2). The EN pin provides shutdown (0.1uA Iq) and can be used for PWM dimming of LEDs (frequencies 100Hz-10kHz). The internal MOSFET has 0.5 ohm RDS(on) and 20V breakdown, limiting maximum output to approximately 18V (typical for 4-6 series white LEDs). The overvoltage protection (OVP) at 22V protects against open-LED conditions. The -KTR-G1 suffix specifies SOT-23-6, tape-and-reel, lead-free.","pin_description":"
