KP3211BSGA High Performance Low Cost Off-line PWM Power Switch
Unlike conventional PWM control, there’s no fixed internal clock in KP3211BSG family to trigger the GATE driver, the switching frequency is changed according to the load condition. The multi-mode PWM control is integrated to simplify circuit design and achieve good line and load regulation without audio noise generated. The peak current limit changes according to the real load condition for low standby power in no load.
KP3211BSG integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Output OVP, On-chip Thermal Shutdown, Over Load Protection (OLP), VDD OVP with Auto Recovery Mode Protection, etc.
FEATURES:
● Integrated with 650V Power MOSFET and HV Startup Circuit
● Optimize Audible Noise, Improve System Stability
● Multi-Mode Control with Audio Noise Free Operation
● Supports Buck and Buck-Boost Topologies
● Default 12V Output with FB floated
● Less than 50mW Standby Power
● Green Mode Operation for High Efficiency
● Good Line and Load Regulation
● Built-in Soft Start
● Build in Protections:
■ Over Load Protection (OLP)
■ Cycle-by-Cycle Current Limiting (OCP)
■ Output OVP
■ VDD OVP, UVLO & Clamp
● Available with SOP-8 Package
