7 Specifications

7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)⁽¹⁾

		MIN	MAX	UNIT
Input voltage	Voltage at VIN⁽²⁾, VOUT⁽²⁾, SW⁽²⁾, EN⁽²⁾, BP⁽²⁾	–0.3	7	V
Input current	Continuous average current into SW ⁽⁴⁾		1.8	A
Input current	Peak current into SW ⁽⁵⁾		3.5	A
Power dissipation		Internally limited
Temperature	Operating, T_A ⁽³⁾	–40	85	°C
	Operating virtual junction, T_J	–40	150
	Storage, T_stg	–65	150

(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 my affect device reliability.

(2) All voltages are with respect to network ground terminal.

(3) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (T_A(max)) is dependent on the maximum operating junction temperature (T_J(max)), the maximum power dissipation of the device in the application (P_D(max)), and the junction-to-ambient thermal resistance of the part/package in the application (θ_JA), as given by the following equation: T_A(max)= T_J(max)–(θ_JA X P_D(max)). To achieve optimum performance, it is recommended to operate the device with a maximum junction temperature of 105°C.

(4) Limit the junction temperature to 105°C for continuous operation at maximum output power.

(5) Limit the junction temperature to 125°C for 5% duty cycle operation.

7.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±2000	V
		Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±1000
		Machine model (MM)	±200

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions.

(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.
