DESCRIPTION/ORDERING INFORMATION

The TPS652x provides one PWM buck controller, two adjustable, synchronous buck regulators, two independent

USB power switches and a supply voltage supervisor (SVS) to provide main power functions for satellite set top

boxes, xDSL and cable modem applications operating off a single 12- to 22-V supply.

The SMPS have integrated switching FETs for optimized power efficiency and reduced external component

count. Each USB switch provides up to 0.5-A (TPS65230) or 1-A (TPS65231) of current as required by

downstream USB devices. All power blocks have thermal and over current/short circuit protection.

The SVS provides two inputs for monitoring positive supply rails. The active-low open-drain output remains low

for at least 180 ms after all supply rails rise above their rising edge threshold. Threshold value for VMON1 input

is set for monitoring a 3.3-V rail without the need for additional external components. Threshold for VMON2 input

is set to 0.8 V and requires resistor dividers on the input to monitor any positive voltage in the system. The

nBOR/nHOT open-drain output is pulled low if the input supply drops below 9.3 V or the chip temperature

approaches the thermal shutdown limit. This allows the system processor to save critical data and shut down

gracefully before the supply fails.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
