The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 28 27 26 25 24 23 22 21 20 19 18 17 16 15 AGND VSENSE NC PWRGD BOOT PH PH PH PH PH PH PH PH PH RT FSEL SS/ENA VBIAS VIN VIN VIN VIN VIN PGND PGND PGND PGND PGND PWP PACKAGE (TOP VIEW) THERMAL PAD AVAILABLE OPTIONS OUTPUT PACKAGED DEVICES OUTPUT PACKAGED DEVICES TA OUTPUT VOLTAGE PLASTIC HTSSOP (PWP)(1)(2) TA OUTPUT VOLTAGE PLASTIC HTSSOP (PWP)(1)(2) 0.9 V TPS54611PWP 1.8 V TPS54614PWP −40°C to 85°C 1.2 V TPS54612PWP −40°C to 85°C 2.5 V TPS54615PWP 40 C to 85 C 1.5 V TPS54613PWP 40 C to 85 C 3.3 V TPS54616PWP (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com. (2) The PWP package is also available taped and reeled. Add an R suffix to the device type (i.e., TPS54616PWPR). See the application section of this data sheet for PowerPAD drawing and layout information. Terminal Functions TERMINAL DESCRIPTION NAME NO. DESCRIPTION AGND 1 Analog ground. Return for slow-start capacitor, VBIAS capacitor, RT resistor FSEL. Make PowerPAD connection to AGND. BOOT 5 Bootstrap input. 0.022-µF to 0.1-µF low-ESR capacitor connected from BOOT to PH generates floating drive for the high-set FET driver. NC 3 No connection PGND 15−19 Power ground. High current return for the low-side driver and power MOSFET. Connect PGND with large copper areas to the input and output supply returns, and negative terminals of the input and output capacitors. PH 6−14 Phase input/output. Junction of the internal high-side and low-side power MOSFETs, and output inductor. PWRGD 4 Power good open drain output. High-Z when VSENSE ≥ 90% Vref, otherwise PWRGD is low. Note that output is low when SS/ENA is low or internal shutdown signal active. RT 28 Frequency setting resistor input. Connect a resistor from RT to AGND to set the switching frequency. SS/ENA 26 Slow-start/enable input/output. Dual function pin which provides logic input to enable/disable device operation and capacitor input to externally set the start-up time. FSEL 27 Frequency select input. Provides logic input to select between two internally set switching frequencies. VBIAS 25 Internal bias regulator output. Supplies regulated voltage to internal circuitry. Bypass VBIAS pin to AGND pin with a high quality, low-ESR 0.1-µF to 1-µF ceramic capacitor. VIN 20−24 Input supply for the power MOSFET switches and internal bias regulator. Bypass VIN pins to PGND pins close to device package with a high quality, low-ESR 1-µF to 10-µF ceramic capacitor. VSENSE 2 Error amplifier inverting input. Connect directly to output voltage sense point. |
