Typical Application Information
General Description
ZS301X 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, ZS301X 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.
ZS301X 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), VDD
Clamping, etc
