GENERAL DESCRIPTION
KP15064SP is a high performance Switch Mode
Power Supply Switcher for low power off-line
application with minimum components in typical
buck solution. This IC has built-in high break down
voltage MOSFET to withstand high surge input.
Unlike conventional PWM control, there’s no fixed
internal clock in KP15064SP 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.
KP15064SP 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)
with Auto Recovery Mode Protection, etc.
