Overview

External Circuit Diagram for On/Off Mode Operation
1.3.2
Constant Current Mode Operation
During constant current operation, the POSx and NEGx pins must be connected to the circuit in the configuration
shown in Figure 2.
Note: An external recirculation diode is required in this configuration otherwise the IC may be damaged.
Figure 2
External Circuit Diagram for Constant Current Mode Operation
The constant current control circuit can operate in two modes; steady state mode and transient mode.
Steady-State Mode
During steady-state operation, the PWM control signal driven at the OUTx pin is controlled by the control loop
shown in Figure 3. The PWM Frequency is programmed via the SPI message # 1. In this message the main period
divider, N, can be set to any value between 79 and 214 -1. The equation for calculating the PWM frequency is:
