Description

AI
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. The 5Vg output is a switched 5-V regulated output with internal current limiting to prevent RESET from being asserted when powering a capacitive load on the supply line. This function is controlled by the 5Vg_ENABLE pin. If there is a short to ground on this output (5Vg output), the output self-protects by operating in a chopping mode. This does, however, increase the output ripple voltage on VOUTduring this fault condition. The TPIC74100 is a switch-mode regulator with integrated switches for voltage-mode control.
