Manufacturer:DALLAS Description:NOTES: 1 Production testing of the device is performed at 25C. Functional operation of the device over a C40C to +85C temperature range is guaranteed by design, characterization and process control. 2 Nominal on time (TONnom ) is defined by the input voltage (VIN), coil inductance (L) and peak current (ILXpkdc) according to the expression: TONnom = {ILX(pkdc) x L/VIN} +200ns 3 This is the time for which the device remains active after the EN pin has been asserted low. This delay is necessary to allow the output to be maintained during dc PWM mode operation. |
