SY5800A
Single Stage Flyback And PFC Controller
With Primary Side Control For LED Lighting
Preliminary datasheet
General Description
The SY5800A is a single stage Flyback and PFC
controller targeting at LED lighting applications. It is a
primary side controller without applying any secondary
feedback circuit for low cost, and drives the Flyback
converter in the quasi-resonant mode to achieve higher
efficiency. It keeps the Flyback converter in constant
on time operation to achieve high power factor.

Typical Applications
Features
• Primary side control eliminates the opto-coupler.
• Valley turn-on of the primary MOSFET to achieve
low switching losses
• 0.3V primary current sense reference voltage leads
to a lower sense resistance thus a lower conduction
loss.
• Internal high current MOSFET driver: 1A sourcing
and 2A sinking
• Low start up current: 15uA typical
• Reliable short LED and Open LED protection
• Power factor >0.90 with single-stage conversion.
• Compact package: MSOP10 and SO8
Applications
• LED lighting
• Down light
• Tube lamp
• PAR lamp
• Bulb

Note 1: Stresses beyond the “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
Note 2: ſJA is measured in the natural convection at TA = 25°C on a low effective single layer thermal conductivity
test board of JEDEC 51-3 thermal measurement standard. Test condition: Device mounted on 2” x 2” FR-4 substrate
PCB, 2oz copper, with minimum recommended pad on top layer and thermal vias to bottom layer ground plane.
Note 3: Increase VIN pin voltage gradually higher than VVIN,ON voltage then turn down to 12V.
