These regulators are designed to operate over a 9 V to 28 V input voltage range to produce a tightly regulated output voltage at load currents of up to 5 A. The wide input voltage range allows them to operate off either a 12 V or 24 V DC input bus system, making them ideal for general purpose and industrial applications. The series includes standard output voltage options ranging from 15 V down to 2.5 V, and down to 1.8 V with adjustment. Only two external capacitors are required for proper operation. The PT6650 series is housed in a lowcost 14-pin SIP (Single In-line Package) and is available in both vertical and horizontal configurations, including surface-mount. = = = = = = 3.3 2.5 5 9 15 12 Volts Volts Volts Volts Volts Volts Note: Back surface of product is conducting metal Pin-Out Information PT Series Suffix (PT1234 x ) Case/Pin Configuration Vertical Horizontal SMD Horizontal, 2-Pin Tab SMD, 2-Pin Tab Horizontal, 2-Pin Ext Tab SMD, 2-Pin Ext Tab Vertical, Side Tab Horizontal, Side Tab SMD, Side Tab Order Suffix Package Code * P D E M L Q F R G B (EED) (EEA) (EEC) (EEM) (EEL) (EEQ) (EEF) (EEE) (EEG) (EEK) * Previously known as package styles 400/410.

(2) See Safe Operating Area curves or contact the factory for the appropriate derating. (3) The STBY* control (pin 3) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit voltage is typcially 1.5 V. Consult the related application note for other interface considerations. (4) The module requires a 560µF electrolytic capacitor at the input and 330µF at the output for proper operation in all applications. In addition, the input capacitance, Cin, must be rated for a minimum of 1.2 Arms of ripple current. For transient or dynamic load applications additional capacitance may be necessary. For more information consult the related application note on capacitor recommendations. (5) During solder reflow of SMD package version do not elevate the module case, pins, or internal component temperatures above a peak of 215°C. For further guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Mount Products,” (SLTA051).

The ripple current rating and less than 120 mΩ equivalent series resistance (ESR) are the major considerations, along with operating temperature, when selecting input capacitors. Tantalum/Os-Con capacitors are not recommended due to a minimum voltage rating of 2× (the max. DC voltage + AC ripple). This is standard practice to ensure reliability. Output Capacitors: The ESR specification of the output capacitor should be a minimum of 50 mΩ *. Electrolytic capacitors have marginal ripple performance at frequencies greater than 400 kHz but excellent low frequency transient response. Above the ripple frequency ceramic capacitors are necessary to improve the transient response and reduce any high-frequency noise components apparent during higher current excursions. Electrolytic capacitors with appropriate ESR values are identified in Table 1-1. In lowtemperature applications (3000 mA 7.3L ×5.7W ×4.1H N/R [1] N/R [1] 1 [2] 1 [2] TPSE337M010R0100 (Vo
