Description

General part information

TPIC74100 Series

The TPIC74100 is a switch-mode regulator with integrated switches for voltage-mode control. With the aid of external components (LC combination), the device regulates the output to 5 V ±3% for a wide input-voltage range.

The TPIC74100 offers a reset function to detect and indicate when the 5-V output rail is outside of the specified tolerance. This reset delay is programmable using an external timing capacitor on the REST pin. Additionally, an alarm (AOUT) feature is activated when the input supply rail Vdriveris below a prescaled specified value (set by the AINpin).

The TPIC74100 has a frequency-modulation scheme to minimize EMI. The clock modulator permits a modulation of the switching frequency to reduce interference energy in the frequency band.
