EC9202 - 200mA PFM Step-up DC-DC Converter

General Description

The EC9202 is a compact PFM step-up DC/DC converter that operates from an input voltage as low as 0.8 Volt.

The low start-up input voltage makes EC9202 specially designed for portable devices from one or two cell battery, delivering up to 200mA load current at VIN=1.8V VOUT=3.3V.

Key Features

  • a band gap reference, trimming technology, current -limited, PFM control scheme which combines the advantages of PWM ( higher output power and efficiency) and those of traditional PFM (ultra-low quiescent current). The internal 0.6 ohm low turn-on resistance NMOS power switch provides stable and high-efficiency operation over a board load current range. The EC9202 devices are available in SOT23-3,SOT23-5 & SOT89 package.  Typical.

200mA PFM Step-up DC-DC Converter With High Efficiency and Low Noise EC9202 General Description The EC9202 is a compact PFM step-up DC/DC converter that operates from an input voltage as low as 0.8 Volt. The low start-up input voltage makes EC9202 specially designed for portable devices from one or two cell battery, delivering up to 200mA load current at VIN=1.8V VOUT=3.3V. Typical efficiency for EC9202 is 85% when VIN>=2.0V VOUT=3.3V ILOAD=1~60mA. Potential applications include low powered consumer products and battery powered portable products. The EC9202 features a band gap reference, trimming technology, current -limited, PFM control scheme which combines the advantages of PWM ( higher output power and efficiency) and those of traditional PFM (ultra-low quiescent current).
