AP3968/69/70
PRIMARY SIDE POWER SWITCHER FOR OFF-LINE SMPS
Description
The AP3968/69/70 consists of a primary side regulation controller and
a high voltage transistor, and is specially designed for off-line power
supplies within 12W output power. Typical applications include
adapter for ADSL and auxiliary supplies.
The AP3968/69/70 operates at pulse frequency modulation (PFM),
and provides accurate constant voltage, constant current (CV/CC)
regulation without requiring an opto-coupler and secondary control
circuitry. It has internal cable compensation function for tight constant
voltage regulation.
The AP3968/69/70 solution has fewer component numbers, smaller
size, and lower total cost.
The AP3968 is packaged in SO-7. The AP3969 is available in PDIP-
7. The AP3970 is available in PDIP-7 and PDIP-8 packages.

Notes:
1. Typical continuous power in a non-ventilated enclosed adapter measured at +50°C ambient.
2. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
3. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
4. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
