This module is the power conversion section of a digital power system which incorporates TI's UCD7230 MOSFET driver IC. The PTD08A010W must be used in conjunction with a digital power controller such as the UCD9240 or UCD9110 family. The PTD08A010W receives control signals from the digital controller and provides parametric and status information back to the digital controller. Together, PowerTrain modules and a digital power controller form a sophisticated, robust, and easily configured power management solution. Operating from an input voltage range of 4.75 V to 14 V, the PTD08A010W provides step-down power conversion to a wide range of output voltages from, 0.7 V to 3.6 V. The wide input voltage range makes the PTD08A010W particularly suitable for advanced computing and server applications that utilize a loosely regulated 8-V, 9.6-V or 12-V intermediate distribution bus. Additionally, the wide input voltage range increases design flexibility by supporting operation with tightly regulated 5-V or 12-V intermediate bus architectures. The module incorporates output over-current and temperature monitoring which protects against most load faults. Output current and module temperature signals are provided for the digital controller to permit user defined over-current and over-temperature warning and fault scerarios. The module uses double-sided surface mount construction to provide a low profile and compact footprint. Package options include both through-hole and surface mount configurations that are lead (Pb) - free and RoHS compatible. 1 2 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.

This is the common ground connection for the VI and VO power connections. VO 4 The regulated positive power output with respect to GND. TEMP 5 Temperature sense output. The voltage level on this pin represents the temperature of the module. IOUT 6 Current sense output. The voltage level on this pin represents the average output current of the module. AGND 7 Analog ground return. It is the 0 Vdc reference for the control inputs. (1) 8 The inhibit pin is a negative logic input that is referenced to AGND. Applying a low-level signal to this pin disables the module and turns off the output voltage. A 10 kΩ pull-up to 3.3 V or 5 V is required if the INH signal is not used. FAULT 9 Current limit flag. The Fault signal is a 3.3 V digital output which is latched high after an over-current condition. The Fault is reset after two complete PWM cycles without an over-current condition (third rising edge of the PWM). SRE 10 Synchronous Rectifier Enable. This pin is a high impedance digital input. A 3.3 V or 5 V logic level signals is used to enable the synchronous rectifier switch. When this signal is high, the module will source and sink output current. When this signal is low, the module will only source current. PWM 11 This is the PWM input pin. It is a high impedance digital input that accepts 3.3 V or 5 V logic level signals up to 1 MHz. VBIAS 12 Bias voltage supply required to power internal circuitry. For optimal performance connect VBIAS to VI.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
