Function
Feedback input for channel 1. Connect FB1 to the center point of an external resistor divider. The feed-
back threshold voltage is 0.6V.
Channel 1 enable pin. Active high. In shutdown, all functions are disabled drawing <1μA supply current.
Do not leave EN1 fl oating.
Power supply input pin. Must be closely decoupled to GND with a 2.2μF or greater ceramic capacitor.
Channel 1 switching node pin. Connect the output inductor to this pin.
Ground
No connection
Power-on reset, active low. Open drain. External resistor (100kΩ) is required. -
Channel 2 enable pin. Active high. In shutdown, all functions are disabled drawing <1μA supply cur-
rent. Do not leave EN2 fl oating.
Feedback input for channel 2. Connect FB2 to the center point of an external resistor divider. The feed-
back threshold voltage is 0.6V.
Exposed paddle. The exposed paddle should be connected to board ground plane and GND. The ground
plane should include a large exposed copper pad under the package for thermal dissipation (see pack-
age outline).
