Non-isolated PFM converters

Product：PN8034M

1.CHIPSDESCRIPTION

The PN8034M consists of an integrated Pulse Frequency Modulator (PFM) controller and power MOSFET，specifically designed for
small power non-isolated switching power supply. PN8034M has internal high voltage start-up circuit and complete intelligent
protections including adjustable Over Current Protection (OCP), Under Voltage Lockout (UVLO) and Over Temperature Protection
(OTP). Excellent EMI performance could be achieved with Pulse Frequency Modulation.
