The recommended operating voltage range for the MC34119P is 10.5V to 16V, with a typical voltage of 12V.
To ensure proper heat-sinking, use a heat sink with a thermal resistance of 1°C/W or less, and apply a thin layer of thermal interface material between the device and heat sink. The heat sink should be mounted to a metal plate or chassis to dissipate heat efficiently.
The maximum output current of the MC34119P is 1.5A per channel, with a total maximum output current of 3A for both channels.
To configure the MC34119P for a specific output voltage, use the voltage divider network consisting of R1, R2, and R3 resistors. The output voltage can be calculated using the formula: Vout = (R2 / R1) * (Vref - Vbe), where Vref is the internal reference voltage (2.5V) and Vbe is the base-emitter voltage of the internal transistor (approximately 0.7V).
The 'Sense' pins (SENSE1 and SENSE2) are used to monitor the output voltage of each channel. They can be connected to the output voltage lines to provide feedback to the internal error amplifier, ensuring accurate regulation of the output voltage.
