General Description
LZC9205 is a high performance, current mode
PWM controller. It provides functions of low
start-up current, fast start-up, fixed switching
frequency. Those features make it to achieve
high efficiency and low standby power with
effective system cost.
At heavy load, the LZC9205 operate in fixed
switching frequency. At light load condition, the
system operates in green mode for high
efficiency. And at zero load, the IC will operate in
BURST mode to enhance power saving.
The LZC9205 offers comprehensive protection
to prevent the circuit from damage under
abnormal conditions. Furthermore, the LZC9205
features frequency swapping and soft driving
function to minimize the noise and improve EMI
performance.
The LZC9205 is offered in SOT23-6 package.
