12
Backplane Driver Clock Input. See Table 1 for input frequency ranges.
BPCLK
13
Analog Ground. Connect to PGND1 and PGND2. See Supply Connections and Layoutsection.
GND
5
Supply Input to the IC. The input voltage range is +2.8V to +5.5V.
IN
6
Regulator Feedback Input for Negative Output, DC-DC 2. Regulates to 0V nominal.
FB2-
7
Regulator Feedback Input for Positive Output, DC-DC 2. Regulates to 1.25V nominal.
FB2+
8
Internal Reference Output. Connect a 0.22μF capacitor from this pin to GND. REF can source up to 50μA.
REF
4
Regulator Feedback Input, DC-DC 1. Regulates to 1.25V nominal.
FB1
3
PIN
Ready Indicator Output, DC-DC 1 and DC-DC 2. Open-drain N-channel output becomes high impedance
when all three outputs are within 10% of regulation.
RDY
2
Shutdown Input. Drive low to enter shutdown mode. Drive high or connect to IN for normal operation. All IC
sections are off when
SHDN
is low.
