NAME
FUNCTION
23
CSN2
Negative Current-Sense Input for the Second Phase. Connect CSN2 to the negative side of the
current-sense element, as shown in Figure 4.
Positive Current-Sense Input for the Second Phase.
1) Connect CSP2 to the positive side of the current-sense resistor or the DCR sense filter
24
CSP2
capacitor of phase 2, as shown in Figure 4.
2) Connect CSP2 to the IOUT pin of the smart power stage (MAX15515). A resistor across
CSP2 and CSN2 sets the current-sense gain, as shown in Figure 3.
See the Current Sense section. To disable phase 2, short CSP2 to BIAS.

EP
Exposed Pad. The substrate of the controller is internally connected to the exposed pad. Connect
EP to the ground plane through multiple vias to maintain low thermal impedance.
