... Rev. 02 — 24 November 2003 M3D797 1. Description The PIP202-12M is designed for use as the power output stage of a synchronous buck DC-to-DC converter. It contains a MOSFET control IC, two power MOSFET transistors and a Schottky diode. By combining the power MOSFETs and the driver circuit into a single component, stray inductances are virtually eliminated, resulting in higher switching frequency, lower switching losses and a compact, effi ...

... Functional description 7.1 Basic functionality Fig 3. Simplified functional block diagram of a synchronous DC-to-DC converter In order to understand the functions performed by the PIP202-12M, consider the requirements of a synchronous DC-to-DC converter output stage, driven from a PWM controller When the input voltage is HIGH, the upper MOSFET must be on and the lower MOSFET must be off. Current fl ...

... After a delay, if the input voltage is still LOW, the gate drive to the lower MOSFET goes HIGH. The lower MOSFET turns on, and the output voltage rises from 0 zero. 7.3 Bootstrap diode A bootstrap diode is integrated into the design of the PIP202-12M between V CB. 9397 750 11943 Product data ...

... Philips Semiconductors At 500 KHz and 20 A output current, the maximum dissipation in each PIP202-12M is typically 4.5 W. The typical thermal resistance from junction to ambient is given in Table PIP202-12M from junction to ambient is 15 K/W. Assuming an ambient temperature the junction temperature ( The thermal resistance between the junction and the printed-circuit board is 5 K/W. ...

... For example, doubling the operating frequency of the circuit in 500 kHz to 1 MHz would increase the power dissipation in each PIP202-12M from output current each PIP202-12M. The maximum switching frequency is limited by thermal considerations, the dissipation in the PIP202-12M device(s) and the thermal resistance from junction to ambient ...
