The 60mΩ built-in Power MOSFET delivers up to 12Vx1A Output from 3.6V Power Supply. The DT9111 has built-in soft-start to limit the inrush current during startup and to limit the amount of overshoot on the output. Protection features in the DT9111 include soft-start, cycle-by-cycle current limit protection and UVLO. The Current Limit is externally adjustable. DT9111 Datasheet Rev1.01, Dec 2015 Page 3

7 APPLICATION INFORMATION Inductor Selection A 2.2~10μH inductor is recommended for most applications. If high efficiency is a critical requirement, a low DCR inductor should be selected. The inductor s saturation current rating should also exceed the peak input current, especially for high load current application. Capacitor Selection Small size ceramic capacitors are ideal for DT9111 application. A combination of 470uF input capacitor and 470uF output capacitor is suggested for most applications. For better voltage filtering, ceramic capacitors with low ESR are recommended. X5R and X7R types are suitable because of their wider voltage and temperature ranges. Diode Selection Using a Schottky diode is recommended in DT9111 applications because of its low forward voltage drop and fast reverse recovery time. The current rating of the Schottky diode should exceed the peak current of the boost converter. The voltage rating should also exceed the target output voltage. Output Voltage Setting Output Voltage is determined by the feedback resistor. The feedback voltage is internally set at 1.25V. For accurate Output Voltage settings, precision 1% resistors are recommended. The formula is shown below: VOUT = (1+R2/R1)*VFB Selection R1=100KΩ, then R2 can be derived from the above formula. Power Sequence In order to assure the normal soft start function for suppressing the inrush current the input voltage should be ready before EN pulls high. Soft-Start The function of soft-start is made for suppressing the inrush current to an acceptable value at the beginning of power on. The DT9111 provides a built-in soft-start function by clamping the output voltage of error amplifier so that the duty cycle of the PWM will be increased gradually in the soft-start period. Current Limiting The current flow through inductor as charging period is detected by a current sensing circuit through the CS pin. As the value comes across the current limiting threshold, the external N-MOSFET will be turned off so that the inductor will be forced to leave charging stage and enter discharging stage. Therefore, the inductor current will not increase over the current limiting threshold. The threshold voltage VCS is 80mV. UVLO The Under-Voltage Lock Out function disables the DT9111 from malfunctioning when the power supply is too low, and recovers when the power supply goes high. DT9111 Datasheet Rev1.01, Dec 2015 Page 7
8 Layout Considerations PCB layout is very important for high frequency switching regulators in order to keep the loop stable and minimize noise. For best performance of the DT9111, the following guidelines must be strictly followed. Input and Output capacitors should be placed close to the IC and connected to ground plane to reduce noise coupling. The GND pin should be connected to a strong ground plane for heat sinking and noise protection. Keep the main current traces as possible as short and wide. The DRV node is with high frequency voltage swing. It should be kept in a smallest area. Place the cs (on CS pin) and feedback components (on FB pin) as close as possible to the IC and keep away from the noisy devices. DT9111 Datasheet Rev1.01, Dec 2015 Page 8
