FAN5331 is a high-efficiency LED driver and OLED supply with 20V integrated switch from FAIRCHILD Semiconductor Corporation. It features 1.6MHz switching frequency, low noise, low R DS(ON): 0.5 Ω, adjustable output voltage, 1A peak switch current, 1W output power capability, low shutdown current: <1µA, cycle-by-cycle current limit, over-voltage protection, fixed-frequency PWM operation, internal compensation, 5-lead SOT-23 package, and is suitable for applications such as cell phones, PDAs, handheld equipment, display bias, and LED bias.
The FAN5331 is a general-purpose, fixed-frequency boost converter designed to operate at 1.6MHz to minimize switching noise measured at the battery terminal of hand-held communications equipment. It features an integrated N-channel switch with low ON-resistance and includes cycle-by-cycle current limiting for protection.
