BOOT 1 A 0.1 mF bootstrap capacitor is required between BOOT and PH. If the voltage on this capacitor falls below the minimum requirement, the high-side MOSFET is forced to switch off until the capacitor is refreshed. VIN 2 Input supply voltage, 3.5 V to 28 V. EN 3 Enable pin. Pull below 1.25V to disable. Float to enable. Programming the input undervoltage lockout with two resistors is recommended. SS 4 Slow start pin. An external capacitor connected to this pin sets the output rise time. VSENSE 5 Inverting node of the gm error amplifier. COMP 6 Error amplifier output, and input to the PWM comparator. Connect frequency compensation components to this pin. GND 7 Ground. PH 8 The source of the internal high-side power MOSFET. 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s): TPS54331-Q1 |
