GENERAL DESCRIPTION
FEATURES
● Extended Burst Mode Control For Improved PWM switching frequency at normal operation is Efficiency and Minimum Standby Power internally fixed and is trimmed to tight range. At no Design load or light load condition, the IC operates in● Audio Noise Free Operation extended ‘burst mode’ to minimize switching loss.
● Fixed 65KHZ Switching Frequency Lower standby power and higher conversion
● Comprehensive Protection Coverage efficiency is thus achieved. o VDD Under Voltage Lockout with VDD low startup current and low operating current Hysteresis (UVLO) contribute to a reliable power on startup and low o Cycle-by-cycle over current threshold standby design with OB2276A. setting for constant output power limiting OB2276A offers complete protection coverage with auto-recovery including Cycle-by-Cycle to current limiting (OCP), over load protection (OLP), Brownout protection, VDD over voltage protection (OVP), over temperature protection (OTP), output l over voltage protection and VDD under voltage tia lockout (UVLO).
