The ZLED7012 is a low-noise, constant-frequency charge pump DC/DC converter for driving up to four LEDs with constant
current at a level controlled via a PCC serial digital interface, providing a uniform and linear brightness progression. Its 20mA
(maximum) current output per LED channel is optimal for low-voltage or battery-powered applications, such as portable
applications powered by 1-cell lithium batteries. The ZLED7012’s current sinks can operate in parallel for driving higher current
LEDs. Only a few, small external components are needed for typical applications. The ZLED7012’s charge pump operates at a
fixed frequency (1MHz typical) with minimal noise and harmonics.
