The AP2008 integrates Pulse-Width-Modulation (PWM) control

circuit into a single chip, mainly designs for power-supply

regulator. All the functions include an on-chip 0.77V reference

output, an error amplifier, an adjustable oscillator, a soft-start,

UVLO, SCP circuitry, and a push-pull output circuit. Switching

frequency is adjustable by trimming CT. During low VCC situation,

the UVLO makes sure that the outputs are off until the internal

circuit is operational normally.

Note: 1. RoHS revision 13.2.2003. Glass and High Temperature Solder Exemptions Applied, see EU Directive Annex Notes 5 and 7.

2. Pad layout as shown on Diodes Inc. suggested pad layout document AP02001, which can be found on our website at
