AP3987CT

HIGH FREQUENCY PRIMARY SIDE POWER SWITCHER FOR OFF-LINE SMPS

Description

Pin Assignments

The AP3987CT is a high performance AC/DC power switcher for

battery charger and adapter applications with built-in high

performance controller and built-in 650V high performance

(Top View)

MOSFET. It can meet less than 10mW standby power for “Super Star”

charger criteria. The device uses Pulse Frequency Modulation (PFM)

method to build Discontinuous Conduction Mode (DCM) Flyback

power supplies.

GND

OTP

VCC

The AP3987CT provides accurate Constant Voltage (CV), Constant

Current (CC) and outstanding dynamic performance without requiring

an opto-coupler. It also eliminates the need of loop compensation

circuitry while maintaining stability.

SO-7

The AP3987CT is equipped with built-in 0.35V output cable drop

compensation.

Features



Primary-Side Control for Eliminating Opto-Coupler

10mW No-Load Input Power

The AP3987CT has internal over temperature protection, and also

provides dedicated pin for external over temperature protection.

Built-In 650V High Performance MOSFET

Flyback Topology in DCM Operation

Built-In 0.35V Cable Compensation for CV

Multiple PWM/PFM Control Mode to Improve Audio Noise and

Efficiency

When the AP3987CT is used with AP4341 or APR3415CT series

synchronous rectifier solution, better under-shoot performance and

higher conversion efficiency can be achieved.



VCS Jitter to Reduce System EMI

Valley-On for the Higher Efficiency and Better EMI

Multiple Protections:

The AP3987CT provides operating frequency dithering function to

improve system EMC performance.



Over Voltage Protection (OVP)

Output Short Circuit Protection (SCP)

Transformer Saturation Protection (TSP) via Primary

Peak Current Limitation

The AP3987CT is packaged in SO-7.



Internal and External Over Temperature Protection (OTP)



Matching AP4341 with Schottky or APR3415CT Series

Synchronous Rectifier Solution

Applications



Adapter/Chargers for Shaver, Cell/Cordless Phones, PDAs, MP3

and Other Portable Apparatus



SO-7 Package

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)



Standby and Auxiliary Power Supplies

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.

2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and

Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)

and <1000ppm antimony compounds.
