Preliminary Datasheet
340kHz, 2A Synchronous DC-DC Buck Converter
General Description
The AP3502E is a 340kHz fixed frequency, current
mode, PWM synchronous buck (step-down) DC-DC
converter, capable of driving a 2A load with high
efficiency, excellent line and load regulation. The
AP3502E exhibits high efficiency at light load. The
device integrates N-channel power MOSFET
switches with low on-resistance. Current mode
control provides fast transient response and
cycle-by-cycle current limit.
The AP3502E employs complete protection to ensure
system security. Including output Over Voltage
Protection, input Under Voltage Lock Out,
programmable Soft Start, Over Temperature
Protection and hiccup mode Short Circuit Protection.
This IC is available in SOIC-8 package.

Will external interference cause 2812 to enter an illegal interrupt during operation?
I made a PWM rectifier. When the DC voltage is below 200V, the DSP runs normally. But when the voltage is increased to 250V, the DSP tends to run wild, mostly because it enters an illegal interrupt (I...
