TYPICAL APPLICATION CIRCUIT
GENERAL DESCRIPTION
6215 is a high performance Quasi Resonant
(QR) Primary Side Regulation (PSR) PWM power
switch with high precision CV/CC control ideal for
charger applications.
In CV mode, 6215 adopts Multi Mode QR
Control which uses the hybrid of AM (Amplitude
Modulation) mode and (Frequency Modulation)
FM mode to improve system efficiency and
reliability. In CC mode, the IC uses PFM control
with line and load CC compensation. The IC can
achieve fast dynamic response. The built-in Cable
Drop Compensation (CDC) function can provide
excellent CV performance
6215 integrates functions and protections of
Under Voltage Lockout (UVLO), VDD over Voltage
Protection (VDD OVP), Cycle-by-cycle Current
Limiting (OCP), Short Load Protection (SLP), On-
Chip Thermal Shutdown, VDD Clamping,
etc .
