General description
The TEA19363LT is a member of the GreenChip family of controller ICs for switched mode power supplies. It is intended for flyback topologies to be used either standalone or together with USB PD or smart charging controllers (like the TEA190x series) at the secondary side. The built-in green functions provide high efficiency at all power levels.
The TEA19363LT is compatible with multiple output voltage applications with a wide output range from 5 V to 20 V in Constant Voltage (CV) mode. When used with a secondary-side controller IC, like the TEA190x series, it supports Constant Current (CC) mode down to 3 V output voltage.

FEATUREs and benefits
General features
• SMPS controller IC supporting smart-charging applications and multiple-output-voltage applications
• Wide output range (5 V to 20 V in CV mode, 3 V to 20 V in CC mode, and 3 V to 6 V in direct charging mode)
• Housed in a small SO10 package
• Adaptive dual supply for highest efficiency over the entire output voltage range
• Integrated high-voltage start-up and X-capacitor discharge
• Continuous VCC regulation during start-up and protection via the HV pin, allowing a minimum VCC capacitor value
• Reduced optocurrent enabling low no-load power (20 mW at 5 V output)
• Fast transient response from 0 to full load
• Minimal audible noise and output voltage ripple in all operating modes
• Integrated soft start

Green features
Enables high efficiency operation over a wide power range via:
• Low supply current during normal operation (0.6 mA without load)
• Low supply current during non-switching state in burst mode (0.2 mA)
• Valley switching for minimum switching losses
• Frequency reduction with fixed minimum peak current to maintain high efficiency at low output power levels

Protection features
The OVP and OTP protections are latched protections. All other protections are safe
restart protections.
• Mains voltage compensated OverPower Protection (OPP)
• OverTemperature Protection (OTP)
• Integrated overpower timeout
• Integrated restart timer for system fault conditions
• Continuous mode protection using demagnetization detection
• Accurate OverVoltage Protection (OVP)
• General-purpose input for safe restart protection; for use with system OverTemperature Protection (OTP)
• Driver maximum on-time protection
• Brownin and brownout protection

APPLICATIONs
• Applications requiring efficient and cost-effective power supply solutions up to 75 W without touchscreen
