RXX 37-pin WQFN-FCRLF Package (Bottom View) Table 5-1. Pin Functions PIN I/O(1) DESCRIPTION NAME NO. AGND 32 G Ground pin, reference point for internal control circuitry. AVIN 3 P Supply rail for the internal VCC LDO. Connect a 1 μF, 25V ceramic capacitor to AGND to bypass this pin. BOOT 26 P Supply rail for the high-side gate driver (boost terminal). Connect the bootstrap capacitor from this pin to PHASE pin. A high temperature (X7R) 0.1 μF or greater value ceramic capacitor is recommended. DNC 6 — Do Not Connect (DNC) pin. This pin is the output of internal circuitry and must be floating. Pin 6 and pin 37 can be shorted together but NO any other PCB connection is allowed on pin 6. EN 27 I Enable pin, an active-high input pin that, when asserted high, causes the converter to begin the soft-start sequence for the output voltage rail. When de-asserted low, the converter de-asserts PG pin and begins the shutdown sequence of the output voltage rail and continue to completion. FB 30 I Positive input of the differential remote sense amplifier, connect to the center point of an external voltage divider. The voltage divider must be connected to output remote sense point. GOSNS 31 I Negative input of the differential remote sense circuit, connect to the ground sense point on the load side. ILIM 1 I Overcurrent limit selection pin. Connect a resistor to AGND to select the overcurrent limit threshold. MODE 36 I The MODE pin selects the switching frequency and sets the operation mode to FCCM or DCM, by connecting a resistor to AGND. SS 29 I The SS pin selects the soft-start time, internal compensation and the fault response, by connecting a resistor to AGND. NC 33, 34, 35 — No connection (NC) pin. There is no active circuit connected inside the IC. These pins can be connected to ground plane or left open. www.ti.com TPS548C26 SLVSGM2 – MARCH 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 3 Product Folder Links: TPS548C26 |
