General Description
50 mA boost converter using Pulse Frequency Modulation, or PFM, technique, in 5-lead SOT-89 or a 5-lead SOT-23 package. Only 3 external components are needed to complete the switcher design.


FEATUREs
• 85% conversion efficiency at 50mA out
• Start-up voltages as low as 900mV
• ±2.5% accurate outputs
• Complete switch design with only 3 external components
• Automatically senses load variations to select the optimal duty cycle and extend conversion efficiencyover a wide range
• External transistor configuration to run as switcher controller
• Shutdown to 0.5µA


APPLICATIONs
• Cellular phones, pagers
• Cameras, video recorders
• Palmtops and PDAs
