description

The TPPM0310 is a power distribution and management device designed primarily for either motherboard or

PCI card 1394a host applications where the power bus for internal 1394 PHY and/or LINK is required. The

TPPM0310is a switch mode regulated output power source configured for use in 1394a system. The step-down

(Buck) regulated voltage is designed for applications that require ≤5 V with load current ≤300 mA (see Output

Voltage Selection Table). The output switch (V ) is fully protected by having over-current limit and thermal

shutdown features.

The TPPM0310 requires a minimum of external standard filter components to regulate the desired output

voltage. This is achieved with an internal oscillator frequency of 250 kHz (typical). The switch mode and

associated circuitry provide efficient regulation with a low quiescent current.

Inthepowerupmode, whenS1andS2arenoconnects, thedevicehasaninternalpulluponbothoftheseinputs

(S1 and S2). This ensures the device and its associated circuitry to regulate the output to 3.3 V. The enable input

has an internal pullup to ensure that the device is enabled on power up sequencing. By applying <0.8 V to the

ENABLE input, the device is disabled.
