(1)
VDD tied to Boot and EN pins. Frequency pin tied to VDD through 121K resistor. VDD_ST = VDD when startu-up occurs. VIN is VDD + D1
voltage (usually 10-50 mv at start-up)
(2)
This is the current into the VDD pin.
(3)
This is the total current into pins VDD, BOOT, SW and FREQ.
(4)
The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature),
θJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is Pdmax = (Tjmax - TA)/ θJA or the number given in the Absolute Maximum Ratings, whichever is lower.
(5)
Junction to ambient thermal resistance (
θJA) is taken from a thermal modeling result, performed under the conditions and guidelines set
forthe in the JEDEC standard JESD51-17. The test board is a 4 layer FR-4 board measuring 102mm x 76mm x 1.6mm with a 3 x 2
array of thermal vias. The ground plane on the board is 50mm x 50 mm. Thickness of copper layers are 36mm/18mm/18mm/36mm
(1.5oz/10z/1oz/1.5ox). Ambient temperature in simulation is 22°C, still air. Power dissipation is 1W. (The DAP is soldered.) Fore more
information on WSON thermal topics, as well as WSON mounting and soldering specifications please refer to (SNOA401) Application
Note 1187 : Leadless Leadframe Package (LLP).
(6)
Exposed DAP soldered to an exposed 1sq. inch area of 1 oz. copper. Thermal resistance can be decreased by using more copper are
to dissipate heat.
(7)
When the EN pin is below VEN_LO, the regulator is shut down; when it is above VEN_HI, the regulator is operating.
