Electrical Characteristics (continued)
(VIN = 1.5V, RSEL = 191kΩ, VOUT = 3.3V, TJ = -40°C to +125°C, typical values are at TJ = +25°C, CIN = 22μF, COUT = 22μF, unless otherwise noted.) (Note 1)
PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS
Thermal Shutdown TJ Rising 165 T °C Threshold SHUT OUT disabled TJ Falling 150
Note 1:
Limits over the specified operating temperature and supply voltage range are guaranteed by design and characterization, and production tested at room temperature only.
Note 2:
Guaranteed by the Required Select Resistor Accuracy parameter.
Note 3:
Output Accuracy in Low-Power mode when IOUT > IOUT_TRANSITION and inductor current is not in Continuous Conduction mode. This accuracy does not include load, line, or ripple.
Note 4:
Output Accuracy in Ultra-Low-Power mode when IOUT < IOUT_TRANSITION. This accuracy does not include load, line, or ripple.
Note 5:
Guaranteed by measuring LX frequency and duty cycle. Maximum duty cycle is a function of input voltage since LX on time varies with VIN.
Note 6:
This is static measurement. The actual peak current limit depends on VIN and L due to propagation delays.
Note 7:
This is the time required to acquire the RSEL value. This time adds to the startup time. www.maximintegrated.com Maxim Integrated | 8 Document Outline General Description Applications Benefits and Features Typical Operating Circuit Absolute Maximum Ratings Package Information TDFN WLP Electrical Characteristics Electrical Characteristics (continued) Typical Operating Characteristics Typical Operating Characteristics (continued) Pin Configurations WLP TDFN Pin Description Functional Diagrams Detailed Description Control Scheme Output Voltage Selection Fixed-Output Voltage Version Features Enable Soft-Start Control Short-Circuit Protection Thermal Shutdown Design Procedure Inductor Selection Input Capacitor Output Capacitor PCB Layout Guidelines Thermal Considerations Ordering Information Revision History
