6 Specifications

6.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VIN Input voltage (all pins) –0.3 7 V
TA Operating temperature –40 85 °C
TJ Maximum operating junction temperature 150 °C
Tstg Storage temperature –55 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(2) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(3) ±500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) The human body model (HBM) is a 100-pF capacitor discharged through a 1.5-kΩ resistor into each pin. The testing is done according JEDECs EIA/JESD22-A114.
(3) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

6.3 Recommended Operating Conditions

MIN NOM MAX UNIT
VIN Input voltage 2.7 5.5 V
TA Operating ambient temperature –40 85 °C
TJ Operating junction temperature –40 125 °C
Cin Input capacitor 2.2 μF
Co Output capacitor 2.2 μF
Cf Flying capacitor 1 μF

FSW Switching frequency 1.5 MHz
SSTIME Soft-start time From the rising edge of enable to 90% output 150 μs
OUTPUT CURRENT
IOUT_nom Maximum output current VOUT remains from 4.8 V to 5.2 V,
3.1 V ≤ VIN ≤ 5.5 V		 120 mA
3.3 V < VIN < 5.5 V 140

THERMAL SHUTDOWN
TSD Shutdown temperature 160 °C
TRC Shutdown recovery 140 °C
(1) When in skip mode, output voltage can exceed VOUT spec because VOUT(skip) = VOUT+0.1.
(2) The TPS60150 device has internal protection circuit to protect IC when VOUT shorted to GND.
