Pin Functions

PIN I/O DESCRIPTION
NO. NAME
A1 VLDO O Output voltage from LDO
A2 AGND — Analog ground
A3 VINLDO I Input voltage pin for LDO
A4(1) VCC I Supply Input for internal reference, has to be connected to VIN1/ VIN2
B1(2) VIN1 I Input voltage pin for buck converter 1
B2 EN1 I Actively high enable input voltage for buck converter 1
B3 EN2 I Actively high enable input voltage for buck converter 2
B4(2) VIN2 I Input voltage pin for buck converter 2
C1 L1 O Switch output from buck converter 1
C2 ENLDO I Actively high enable input voltage for LDO
C3 MODE I Set low to enable Power Save Mode. Pulling this PIN to high forces the device to operate in PWM mode over the whole load range.
C4 L2 O Switch output from buck converter 2
D1 PGND1 — Power ground
D2 FB1 I Feedback input from buck converter 1
D3 FB2 I Feedback input from buck converter 2
D4 PGND2 — Power ground
(1) VCC must be the highest input for the device to function correctly.
(2) VIN1/VIN2 must be connected to VCC.
