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.
