MCP1252/53 is a regulated charge pump that can be used for white LED drive in parallel, the drive capability can be up to 120mA. The control of the brightness of LED can be done through a control signal which applied to /SHDN pin. Only need a small capacitance external capacitor and no inductor is required, so it is very easy to use with no EMI issues.
For drive LED in series, we have MCP1650 boost controller, the voltage output of MCP1650 can up to 100V with 5W power output, so it is easy to drive many LEDs is series, datasheet of MCP1650 been put in Microchip's website, you can get it from website or contact Microchip Taiwan office.
