Function Description Operation The FP6292 is a current mode boost converter. The constant switching frequency is 1.2MHz and operates with pulse width modulation (PWM). Build -in 24V / 0.75A MOSFET provides a high output voltage. The control loop architecture is peak cu rrent mode control; therefore slope compensation circuit is added to the current signal to allow stable operation for duty cycles larger than 50%. Soft Start Function Soft start circuitry is integrated into FP6292 to av oid inrush current during power on. After the IC is enabled, the output of error amplifier is clamped by the internal soft-start function, which causes PWM pulse width increasing slowly and thus reducing input surge current. Over Voltage Protection (OVP) In some condition, the resistive divider may be unconnected, which will cause PWM signal to operate with maximum duty cycle and output vo ltage is boosted higher and higher. The power MOSFET will be turned off immediately, when the output voltage exceeds the OVP threshold level. The FP6292’s OVP threshold is 24V. Over Temperature Protection (OTP) FP6292 will turn off the power MOSFET automatically when the internal junction temperature is over 150°C. The power MOSFET wake up when the junction temperature drops 30 °C under the OTP threshold temperature.

No liability is assumed as a result of the use of this product. No rights under any patent accompany the sales of the product. Inductor Selection Inductance value is decided based on different condition. 4.7 to 22 µH inductor value is recommended for general application circuit. There are three important inductor specifications, DC resistance, saturation current and core loss. Low DC resistance has better power efficiency. Also, it avoid inductor saturation which will cause circuit system unstable and lower core loss at 1.2MHz. Capacitor Selection The output capacitor is required to maintain the DC voltage. Low ESR capacitors are preferred to reduce the output voltage ripple. Ceramic capa citor of X5R and X7R are recommended, which have low equivalent series resistance (ESR) and wider operation temperature range. Diode Selection Schottky diodes with fast recovery times and low forward voltages are recommended. Ensure the diode average and peak current rating exceed the average output current and peak inductor current. In addition, the diode’s reverse breakdown voltage must exceed the output voltage. Output Voltage Programming The output voltage is set by a resistive voltage di vider from the output voltage to FB. The output voltage is: 2R 1R1V24.1VOUT The recommended resistor value is summarized below: Layout Considerations 1. The power traces, consisting of th e GND trace, the LX trace and the V CC trace should be kept short, direct and wide. 2. LX、L and D switching node, wide and short trace to reduce EMI. 3. Place CIN near VCC pin as closely as possible to maintain input voltage steady and filter out the pulsing input current. 4. The resistive divider R1and R2 must be connected to FB pin directly as closely as possible. 5. FB is a sensitive node. Please keep it away from switching node, LX. 6. The GND of the IC, C IN and C OUT should be connected close together directly to a ground plane. VOUT (V) R1 (kΩ) R2 (kΩ) 5 140 46 12 140 16 15 145 13 18 150 11
