Description

General part information

TPS65230 Series

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.
