... Rev. 02 — 21 February 2003 M3D797 1. Description The PIP250M is a fully integrated synchronous buck converter intended for use as a point-of-load regulator. It contains two N-channel power MOSFETs, a Schottky diode and a voltage mode, pulse width modulated (PWM) controller. The controller features include overcurrent and overvoltage protection and undervoltage lockout functions. ...

... Functional description 7.1 Pin functions 7.1.1 Output stage supply (V The power output stage of the PIP250M consists of two N-channel, power MOSFETs and a Schottky diode configured as a synchronous buck converter. The drain of the upper MOSFET is connected to the positive conversion supply (V source of the lower MOSFET is connected to power ground (V diode is connected between the source and drain of the lower MOSFET ...

... Regulated output voltage The reference voltage of the PIP250M is 0.8 V. The regulated output voltage is set using a resistive divider as shown in close as possible to the FB pin. Both resistors should be less than order to avoid noise coupling. The 68 nF capacitor across the upper resistor improves the control loop stability by adding a small amount of phase margin ...

... If three overcurrent pulses are detected, the PIP250M latches off and produces no more pulses until it has been reset. To reset the PIP250M, the supply voltage (V must be reduced below the power down reset threshold and then increased back ...

... If the voltage on FB exceeds the overvoltage protection (OVP) threshold (1 V) for longer than overvoltage condition is detected, the gate drive signals to the MOSFETs are disabled, and the PIP250M latches off. To reset the latch, the PIP250M must be powered down by reducing V threshold and then increasing V If the voltage on FB drops below the undervoltage protection (UVP) threshold (0 ...
