6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Input voltage VIN, PG –0.3 7.5 V
FB, COMP, PCL, CS, EN –0.3 VIN + 0.3 V
Output voltage VOUT, SS –0.3 7.5 V
PG terminal sink current 0.001 5 mA
Maximum operating junction temperature, TJ –55 220 °C
Storage temperature, Tstg –55 220 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. 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, all pins(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
TJ Operating junction temperature –55 210 °C
tR EN Rise time (10% to 90%) for EN signal 100 µs
tR VIN Rise time (10% to 90%) for VIN = EN 1 ms

6.4 Thermal Information

THERMAL METRIC(1)(3) TPS7H1201-HT UNIT
HKS (CFP)(2)
16 PINS
RθJA Junction-to-ambient thermal resistance 75.4 °C/W
RθJC(top) Junction-to-case (top) thermal resistance 0.4 °C/W
RθJB Junction-to-board thermal resistance 64.8 °C/W
ψJB Junction-to-board characterization parameter 53.5 °C/W
RθJC(bot) Junction-to-case (bottom) thermal resistance N/A °C/W
(1) Maximum power dissipation may be limited by overcurrent protection.
(2) Power rating at a specific ambient temperature TA should be determined with a junction temperature below 220°C. This is the point where distortion starts to substantially increase. Thermal management of the PCB should strive to keep the junction temperature at or below 220°C for best performance and long-term reliability.
(3) Test board conditions:
  1. 2.5 inches × 2.5 inches, 4 layers, thickness: 0.062 inch
  2. 2-oz. copper traces located on the top of the PCB
  3. 2-oz. copper ground planes on the 2 internal layers and bottom layer
  4. 48 (0.010-inch) thermal vias located under the device package
