The SSL3252 is a photo flash LED driver designed for battery operated mobile devices such as mobile phones and PDAs. The boost converter delivers high performance and drives a single or dual high brightness LED at up to 500 mA with over 85 % efficiency. The driver can be programmed to operate in Flash mode, Torch mode, Assist light mode, or Indicator mode.
The small silicon size and the high internal switching frequency of 2 MHz minimize the size of the application and make the SSL3252 very suitable for mobile phones where space is limited, and only requiring three external components. System protection has been a very important part of the SSL3252 design, so a time-out function can be programmed to prevent overstressing the LED, and the driver itself is protected from overheating.
