DC to DC Converter and Piezoelectric Horn Driver
Product Specification
Electrical Characteristics
Limits apply at Vdd=3V, Vss=0V, Cvo=10uF, T
Typical values are at T
Notes on Electrical Characteristics:
1. DC-DC converter in high boost mode (normal VO=10V) can draw current pulses of greater than 1 Amp and is therefore very
sensitive to series resistance. Critical components of this resistance are the inductor DC resistance, the internal resistance of the
battery and the resistance in the connections from the inductor to the battery, from the inductor to the LX pin and from the Vss2 pin
to the battery. In order to function properly under full load at Vdd=2V, the total of the inductor and the interconnect resistances
should not exceed 0.3 ohm. The internal battery resistance should be no more than 0.5 ohm and a low ESR capacitor of 10uF or
more should be connected in parallel with the battery to average current over the boost converter cycle.
2. In the Electrical Characteristics Table, wherever a specific VO value is listed under test conditions, the VO is forced externally
with the inductor disconnected and the DC-DC converter is not running.
3. The brown-out threshold voltage is the VO voltage at which the horn will be disabled.
4. The limits shown are 100% tested at 25C only. Test limits are guard-banded based on temperature characterization to guarantee
compliance at temperature extremes.
