PRODUCTION DATA
The LV2862 has two fixed frequency options and implements peak current mode control. The output voltage is compared through external resistors on the FB pin to an internal voltage reference by an error amplifier that drives the internal COMP node. An internal oscillator initiates the turnon of the high-side power switch. The error amplifier output is compared to the high-side power switch current. When the power switch current reaches the level set by the internal COMP voltage, the power switch is turned off. The internal COMP node voltage increases and decreases as the output current increases and decreases. The device implements a current limit by clamping the COMP node voltage to a maximum level.
