Feature
- 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
- Suited for mobile charger applications that require low Common-Mode Noise (CMN) distortion (meeting the IEC EN62684 specification)
- Adaptive dual supply for highest efficiency over the entire output voltage range
- Integrated high-voltage start-up
- Continuous VCC regulation during start-up and protection via the HV pin, allowing a minimum VCC capacitor value
- Reduced opto current 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
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 the 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
All protections are safe-restart protections.
- Mains voltage compensated OverPower Protection (OPP)
- OverTemperature Protection (OTP)
- Integrated overpower time-out
- 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
