Switching boost supply

Very basic boost converter. This takes 3-6 volts from a battery pack up to 30 volts for 10 white LEDs in series. The coil is 33uH and the operating frequency is approximately 100KHz with 91% duty cycle. I will use an 8 pin ATTiny microcontroller to monitor voltage and generate the PWM with the internal 64MHz PLL on Timer1.
