5 / 27 page TLV620612-Q1 www.ti.com SLVSB93A – JANUARY 2012 – REVISED MARCH 2012 PIN ASSIGNMENTS TERMINAL FUNCTIONS TERMINAL I/O DESCRIPTION NAME NO. AGND 3 IN Analog GND supply pin for the control circuit. Analog VIN power supply for the control circuit. Must be connected to PVIN and input AVIN 7 IN capacitor. This is the enable pin of the device. Pulling this pin low forces the device into shutdown EN 5 IN mode. Pulling this pin high enables the device. This pin must be terminated. Feedback pin for the internal regulation loop. Connect the external resistor divider to this pin. FB 4 IN In the case of fixed output voltage option, connect this pin directly to the output capacitor. MODE pin = high forces the device to operate in fixed-frequency PWM mode. MODE pin = MODE 6 IN low enables the power-save mode with automatic transition from PFM mode to fixed- frequency PWM mode. This pin must be terminated. PGND 1 PWR GND supply pin for the output stage PVIN 8 PWR VIN power-supply pin for the output stage This is the switch pin and is connected to the internal MOSFET switches. Connect the SW 2 OUT external inductor between this terminal and the output capacitor. For good thermal performance, this pad must be soldered to the land pattern on the PCB. Thermal pad – – This pad should be used as device GND. Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s) :TLV620612-Q1 |
