PRIMARY SIDE CONTROL SMPS WITH BUILT-IN MOSFET
DESCRIPTION
SD6854 is a primary side control SMPS with built-in MOSFET. It
features programmable cable drop compensation function, PFM
technology and CV/CC control loop with high reliability and
average efficiency.
With SD6854, opto-couple and Y capacitor, secondary feedback
control, loop compensation circuit can be eliminated for
reducing cost.
In a certain output voltage range, output voltage can be set
through feedback resistor, and output current also can be set
through peak current sense resistor. Setting cable drop
compensation and peak current compensation are also
available for optimized output voltage/current regulation.
FEATURES
* Built-in high voltage MOSFET
* Primary side control
* Low start-up current
* Leading edge blanking
* Pulse-Frequency Modulation(PFM)
* Overvoltage protection
* Undervoltage lockout
* Over temperature protection
* Cycle by cycle current limiting
* Open loop protection
* Cable drop compensation
* Peak current compensation
APPLICATIONS
* Mobile charger
* Adaptor with small power
* charger for MP3 and other portable
apparatus
* Stand-by power supply
