8 / 16 page  Application Notes ATH Series of Wide-Output Adjust Power Modules (3.3/5-V Input) North America (USA): 1-888-41-ASTEC Europe (UK): 44(1384)842-211 Asia (HK): 852-2437-9662 Features of the ATH Family of Non-Isolated Wide Output Adjust Power Modules Point-of-Load Alliance The ATH family of non-isolated, wide-output adjust power modules are optimized for applications that require a flexible, high performance module that is small in size. These products are part of the “Point-of-Load Alliance” (POLA), which ensures compatible footprint, interoperability and true second sourcing for customer design flexibility. The POLA is a collaboration between Texas Instruments, Artesyn Technologies, and Astec Power to offer customers advanced non-isolated modules that provide the same functionality and form factor. Prod- uct series covered by the alliance includes the ATH06 (6 A), ATH10 (10 A), ATH12/15 (12/15 A), ATH18/22 (18/22 A), and the ATH26/30 (26/30 A). From the basic, “Just Plug it In” functionality of the 6-A modules, to the 30-A rated feature-rich ATH30, these products were designed to be very flexible, yet simple to use. The features vary with each product. Table 3-1 provides a quick reference to the available features by product and input bus voltage. Table 3-1; Operating Features by Series and Input Bus Voltage For simple point-of-use applications, the ATH06 provides operating features such as an on/off inhibit, output volt- age trim, pre-bias startup (3.3/5-V input only), and over-current protection. The ATH10 (10 A), and ATH12/ 15 (12/15 A) include an output voltage sense, and margin up/down controls. Then the higher output current, ATH18/22 and ATH26/30 products incorporate over-tem- perature shutdown protection. All of the products referenced in Table 3-1 include Auto-Track™. This is a feature unique to the ATH family, and was specifically designed to simplify the task of sequencing the supply voltage in a power system. These and other features are described in the following sections. Soft-Start Power Up The Auto-Track™ feature allows the power-up of multiple ATH modules to be directly controlled from the Track pin. However in a stand-alone configuration, or when the Auto-Track™ feature is not being used, the Track pin should be directly connected to the input voltage, Vin (see Figure 3-1).

This allows the module to power up entirely under the control of its internal soft-start circuitry. When power up is under soft-start control, the output voltage rises to the set-point at a quicker and more linear rate.
