PC POWER SUPPLY

DESCRIPTION

The UTC

3513

is designed to provide protection circuits,

power good output (PGO) indicator, fault protection output

(FPOB) and a PSONB control for PC switching power supply

systems.

The protection circuits include over voltage protection

(OVP), under voltage protection (UVP) and over current

protection(OCP) monitoring for 3.3V, 5V and two 12V.

When 3.3V, 5V or 12V voltage is decreasing to 2.68V, 4.3V

and 9.9V respectively, the under voltage protection (UVP)

function will be enabled. FPO will be set to high to turn off the

PWM controller IC. Toggling the PSONB from low to high will

reset the fault protection latch.

The voltage difference across external current shunt is used

for OCP functions. An external resistor can be used to adjust

protection threshold.

The power supply is turned on after 38mS delay time when

PSONB signal is set from high to low. To turn off power

supply, PSONB signal is set from low to high with the delay

time 38mS. The PGI circuitry provides a power-down warning

signal for PGO. When PGI input is lower than the internal

1.20V reference voltage, PGO signal is pulled low.

The device is available in two versions: UTC

3513E/3513F.

Specially, fan control function is available in OTP/FC pin of

UTC

3513F.
