... TOSHIBA CMOS Integrated Circuit Silicon Monolithic Buck DC-DC Converter IC The TCV7100F is a single-chip buck DC-DC converter IC. The TCV7100F contains high-speed and low-on-resistance power MOSFETs for the main switch and synchronous rectifier to achieve high efficiency. Features • Enables load current (I external components. ...

... Generally, ΔI should be set to approximately 30% of the maximum output current. Since the maximum L output current of the TCV7100F is 2.5 A, ΔI rating greater than the peak output current of 2 the inductor current rating is exceeded, the inductor becomes saturated, leading to an unstable DC-DC converter operation. ...

... The TCV7100F provides thermal shutdown. When the junction temperature continues to rise and reaches T (150°C typ.), the TCV7100F goes into thermal shutdown and shuts off the power supply. TSD has a hysteresis of about 15°C (typ.). The device is enabled again when the junction temperature has dropped by approximately 15° ...

... The input voltage, output voltage, output current and temperature conditions should be considered when selecting capacitors, inductors and resistors. These components should be evaluated on an actual system prototype for best selection. • External components such as capacitors, inductors and resistors should be placed as close to the TCV7100F as possible. • The TCV7100F has an ESD diode between the EN and V − ...
