Features and benefits
2.1 Distinctive features
• Complete functionality as a combination with TEA19162T
• Integrated high-voltage start-up
• Integrated high-voltage level shifter (LS)
• Extremely fast start-up (< 500 ms at Vmains = 100 V (AC))
• Continuously VSUPIC regulation via the SUPHV pin during start-up
and protection,
allowing minimum SUPIC capacitor values
• Operating frequencies are outside the audible area at all
operating modes
• Integrated soft start
• Power good function
• Maximum 500 kHz half-bridge switching frequency
2.2 Green features
• Extremely high efficiency from low load to high load
• Compliant with Energy using Product directive (EuP) lot 6
• Excellent no-load input power (< 75 mW for
TEA19161T/TEA19162T/TEA1995T
combination)
• Regulated low optocurrent, enabling low no-load power consumption
• Very low supply current during non-switching state in burst mode
• Transition between different operation modes
(high-power/low-power/burst mode)
occur at integrated, externally adjustable power levels
• Adaptive non-overlap time
2.3 Protection features
• Supply undervoltage protection (UVP)
• Overpower protection (OPP)
• Integrated adjustable overpower timeout
• Adjustable latch or restart function for overpower protection
• On-chip overtemperature protection (OTP)
• Capacitive mode regulation (CMR)
• Accurate overvoltage protection (OVP)
• Maximum on-time protection for low-side and high-side driver
output
• Overcurrent protection (OCP)
• Disable input
