GENERAL DESCRIPTION
DP2525 is a low cost and high performance
Primary Side Regulation (PSR) controller for
offline small power converter applications which
can provide very tight output voltage regulation
(CV) and output current control (CC) ideal for
charging applications.
In CV mode, DP2525 adopts Multi Mode 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 audio noise free operation and optimized
dynamic response. The built-in Cable Drop
Compensation (CDC) function can provide
excellent CV performance.
DP2525 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), Pin
Floating Protection, VDD Clamping, etc.
