Electrical Characteristics (continued)
(VIN = VEN = 3.6V, VOUT = 12V, TJ = -40°C to +125°C, typical values are at TJ = +25°C, unless otherwise noted. (Note 1))
PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS
POK Output Voltage Low (TDFN Package VPOK_L IPOK = 2mA 0.4 V Only) POK Leakage Current I (TDFN Package Only) POK_LK VPOK = 5.5V, TJ = +25°C -1 +1 μA Overtemperature T Lockout Threshold OTLO TJ rising, 15°C typical hysteresis 165 °C
Note 1:
Limits are 100% production tested at TJ = +25°C. Limits over the operating temperature range are guaranteed through correlation using statistical quality control (SQC) methods.
Note 2:
Output accuracy does not include load, line, or ripple.
Note 3:
This is a static measurement. The actual peak current limit depends upon VIN and the inductor due to propagation delays.
Note 4:
Measured opened loop. Propagation delays not included. www.maximintegrated.com Maxim Integrated | 8 Document Outline General Description Applications Benefits and Features Typical Application Circuit Absolute Maximum Ratings Package Information WLP TDFN Electrical Characteristics Electrical Characteristics (continued) Typical Operating Characteristics Typical Operating Characteristics (continued) Pin Configurations WLP TDFN Pin Description Functional Diagram Functional Block Diagram Detailed Description Undervoltage Lockout Enable and Disable Soft-Start Output Short-Circuit Protection Thermal Shutdown Device Functional Modes Light Load Efficiency Mode PWM Mode Applications Information Typical Application Design Requirements Detailed Design Procedure Programming the Output Voltage Inductor Selection Input and Output Capacitor Selection Layout Guidelines Ordering Information Revision History
