11 / 13 page PRODUCT SPECIFICATION FAN5607 REV. 1.0.0 6/22/04 11 Selecting Capacitors It is important to select the appropriate capacitor types and the values for use with the FAN5607. These capacitors deter- mine parameters such as power efficiency, maximum sus- tainable load current by the charge pump, input and output ripple and start-up process. In order to reduce ripple, both CIN and COUT should be low ESR capacitors. Increasing the COUT capacitor reduces the output ripple voltage. However this will increase the power- on time. The CIN value controls input ripple. If necessary, this ripple can be further reduced by powering the FAN5607 through the RC input filter, as shown in Figure 7. Two low ESR bucket capacitors of value between 0.1µF to 1µF, should be used for best efficiency in boost mode. The bucket capacitor, CAP1 = CAP2 = 1µF is recommended, if the FAN5607 is required to start at battery voltage lower than 3V. PC Board Layout For best performance, a solid ground plane is recommended on the back side of the PCB. The ground tails of CIN and COUT should be connected together close to the GND pin of IC. 0.22 Ω 10 µF 4.7 µF Input Power Supply VIN GND FAN5607 Figure 7. Battery Ripple Reduction |
