POWER MANAGEMENT IC FOR DIGITAL SET TOP BOXES

The TPS65230 , TPS65231 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. By Texas Instruments
