This module is the power conversion section of a digital power system which incorporates TI's UCD7230 MOSFET driver IC. The PTD08A015W must be used in conjunction with a digital power controller such as the UCD9240 or UCD9110 family. The PTD08A015W 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 PTD08A015W 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 PTD08A015W 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. The PTD08A015W is constructed using through-hole pins and is 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.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

An additional 330 µF bulk capacitor rated for a minimum of 500mA rms of ripple current is recommended. When operating at frequencies > 500kHz the 22 µF ceramic capacitor is only recommended. Refer to the UCD9240 controller datasheet and user interface for application specific capacitor specifications. A 47 µF ceramic output capacitor is required for basic operation. An additional 330 µF bulk capacitor is recommended for improved transient response. When operating at frequencies > 500kHz the 47 µF ceramic capacitor is only recommended. Refer to the UCD9240 controller datasheet and user interface for application specific capacitor specifications. 5,000 µF is the calculated maximum output capacitance given a 1V/msec output voltage rise time. Additional capacitance or increasing the output voltage rise rate may trigger the overcurrent threshold at start-up.

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. INH (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.

Figure 27 shows the UCD9240 power supply controller working in a system which requires the regulation of four independent power supplies. The loop for each power supply is created by the respective voltage outputs feeding into the Error ADC differential inputs, and completed by DPWM outputs feeding into the UCD7230 drivers which are shown on the PTD08A0x0W modules. 10 Submit Documentation Feedback Copyright © 2009–2010, Texas Instruments Incorporated Product Folder Link(s): PTD08A015W PTD08A015W www.ti.com SLTS296A – OCTOBER 2009 – REVISED FEBRUARY 2010 UCD9240 Graphical User Interface (GUI) When using the UCD9240 digital controller along with digital PowerTrain modules to design a digital power system, several internal parameters of the modules are required to run the Fusion Digital Power Designer GUI.

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) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
