Product Description

General Description

The CYH8118 Series is a Synchronous step-up DC/DC Converter with PFM Control. With the CYH8118 Series, a step-up switching DC/DC converter can be configured by using an external coil, capacitor. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from being damaged.


Features
  • External parts: Coil, capacitor
  • Output voltage: 2.1V to 5.5V
  • Maximum Oscillation frequency :300KHz
  • Accuracy of ±2%
  • High efficiency: 95%
  • Package: SOT23-5 and SOT89

Applications    
  • Digital cameras
  • Electronic notebooks and PDAS
  • Portable CD/MD players
  • Cameras , video equipment
  • Communications equipment
  • Power supply for microcomputers
