Pin Functions

PIN I/O DESCRIPTION
NAME WCSP HotRod
EN A3 11 I Enable input. (1 enabled, 0 disabled). It must not be left floating
FB D2 5 I Voltage feedback of adjustable versions, must be connected to VOUT on fixed output voltage versions1
GND B1 2,9 Ground for Power stage and Control stage
ILIM0 B2 10 I Programmable inrush current limit input works together with lLIM1. See table on page 1.
It must not be left floating
ILIM1 B3 See (1) I Programmable inrush current limit input works together with lLIM0.
See Efficiency vs Output Current on page 1. Do not leave floating
L1 A1 1 Connection for Inductor
L2 C1 3 Connection for Inductor
PFM/PWM C2 6 I 0 for PFM mode 1 for forced PWM mode. It must not be left floating
PG C3 8 O Power good open drain output
SS D3 7 I Adjustable Soft-Start. If left floating default soft-start time is set
VIN A2 12 I Supply voltage for power stage and control stage
VOUT D1 4 O Buck-boost converter output
(1) Only available with DSBGA package, for VQFN package ILIM1 is internally connected to voltage level > VIH
