PhotonIC� Four Output Driver For White LEDs

The CM9140 is an adaptive fractional switched capaci- tor (charge pump) Regulator optimized for driving four white LEDs Each LED's driver current is matched to within 2% for uniform intensity. The CM9140 supports an input voltage range of 2.9V to 5.5V with undervolt- age lockout. A failure detection circuit prevents the loss of power when one or more LEDs fail (short or open). Internal over-temperature and over-current manage- ment provide short Circuit Protection By California Micro Devices Corporation
