6 / 30 page LMZ31506H SNVS996 – JULY 2013 www.ti.com PIN DESCRIPTIONS TERMINAL DESCRIPTION NAME NO. 1 2 Zero VDC reference for the analog control circuitry. Connect AGND to PGND at a single point. Connect near AGND the output capacitors. 34 45 8 Inhibit and UVLO adjust pin. Use an open drain or open collector output logic to control the INH function. A INH/UVLO resistor divider between this pin, AGND and VIN adjusts the UVLO voltage. Tie both pins together when 9 using this control. 3 4 5 15 16 18 Do not connect. These pins must remain isolated from one another. Do not connect these pins to AGND or DNC 19 to any voltage. These pins must be soldered to isolated pads. 20 22 23 30 31 32 36 PGND 37 Common ground connection for the PVIN, VIN, and VOUT power connections. 38 10 11 12 Phase switch node. These pins should be connected by a small copper island under the device for thermal PH 13 relief. Do not place any external component on this pin or tie it to a pin of another function. 14 17 46 PWRGD 33 Power good fault pin. Asserts low if the output voltage is low. A pull-up resistor is required. 39 PVIN 40 Input switching voltage. this pin supplies voltage the power switches of the converter. 41 This pin automatically selects between RT mode and CLK mode. An external timing resistor adjusts the RT/CLK 35 switching frequency of the device. In CLK mode, the device synchronizes to an external clock. Remote sense connection. Connect this pin to VOUT at the load for improved regulation. This pin must be SENSE+ 44 connected to VOUT at the load, or at the device pins. Slow-start and tracking pin. Connecting an external capacitor to this pin adjusts the output voltage rise time. SS/TR 6 A voltage applied to this pin allows for tracking and sequencing control. Slow-start or track feature select. Connect this pin to AGND to enable the internal SS capacitor with a SS STSEL 7 interval of approximately 1.1 ms. Leave this pin open to enable the TR feature. VADJ 43 Connecting a resistor between this pin and AGND sets the output voltage. VIN 42 Input bias voltage pin. Supplies the control circuitry of the power converter. 6 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: LMZ31506H |
