SP6850
Green-Mode PWM Controller
DESCRIPTION
The SP6850 is the current mode PWM controller
with green-mode power-saving operation, to meet the
low standby-power needs of low-power SMPS. This
green-mode function enables the power supply to
easily meet even the strictest power conservation
requirements. The functions such as the leading-edge
blanking of the current sensing, internal slope
compensation and the small package provide the high
efficiency / low cost for SMPS power applications.
SP6850 is processed by BiCMOS fabrication, that
enables reducing the start-up current and the
operating current. SP6850 is available by SOT-23-6L
/ DIP-8P packages.
