6.1 Absolute Maximum Ratings

T_A = 25°C (unless otherwise noted)⁽¹⁾

		MIN	MAX	UNIT
	V_IN to P_GND	–0.3	30	V
	V_SW to P_GND , V_IN to V_SW	–0.3	30	V
	V_SW to P_GND, V_IN to V_SW (<10 ns)	–7	33	V
	V_DD to P_GND	–0.3	6	V
	PWM, SKIP# to P_GND	–0.3	6	V
	BOOT to P_GND	–0.3	35	V
	BOOT to P_GND (<10 ns)	–2	38	V
	BOOT to BOOT_R	–0.3	6	V
	BOOT to BOOT_R (duty cycle <0.2%)		8	V
P_D	Power Dissipation		8	W
T_J	Operating Temperature	–40	150	°C
T_stg	Storage temperature range	–55	150	°C

(1) Stresses above those listed in 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)⁽¹⁾	±2000		V
V_(ESD)	Electrostatic discharge	Charged Device Model (CDM)⁽²⁾	±500		V

(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

T_A = 25°C (unless otherwise noted)

			MIN	MAX	UNIT
V_DD	Gate Drive Voltage		4.5	5.5	V
V_IN	Input Supply Voltage ⁽¹⁾			24	V
I_OUT	Continuous Output Current	V_IN = 12 V, V_DD = 5 V, V_OUT = 1.8 V, ƒ_SW = 500 kHz, L_OUT = 0.29 µH⁽²⁾		25	A
I_OUT-PK	Peak Output Current⁽³⁾			60	A
ƒ_SW	Switching Frequency	C_BST = 0.1 µF (min)		2000	kHz
	On-Time Duty Cycle			85%
	Minimum PWM On-Time		40		ns
	Operating Temperature		–40	125	°C

(1) Operating at high V_IN can create excessive AC voltage overshoots on the switch node (V_SW) during MOSFET switching transients. For reliable operation, the switch node (V_SW) to ground voltage must remain at or below the Absolute Maximum Ratings.

(2) Measurement made with six 10 µF (TDK C3216X5R1C106KT or equivalent) ceramic capacitors placed across V_IN to P_GND pins.

(3) System conditions as defined in Note 2. Peak Output Current is applied for t_p = 10 ms, duty cycle ≤1%

6.4 Thermal Information

T_A = 25°C (unless otherwise noted)

THERMAL METRIC		MIN	TYP	MAX	UNIT
R_θJC	Junction-to-Case Thermal Resistance (Top of package)⁽¹⁾			22.8	°C/W
R_θJB	Junction-to-Board Thermal Resistance⁽²⁾			2.5	°C/W

(1) R_θJC is determined with the device mounted on a 1 inch² (6.45 cm²), 2 oz (0.071 mm thick) Cu pad on a 1.5 inch x 1.5 inch, 0.06 inch (1.52 mm) thick FR4 board.

(2) R_θJB value based on hottest board temperature within 1 mm of the package.
