Description

General part information

LT3692A Series

The LT3692A is a dual current mode PWM step-down DC/DC converter with two internal 3.8A switches. Independent input voltage, shutdown, feedback, soft-start, UVLO current limit and comparator pins for each channel simplify complex power supply tracking and sequencing requirements.To optimize efficiency and component size, both converters have a programmable maximum current limit and are synchronized to either a common external clock input, or a resistor settable fixed 250kHz to 2.25MHz internal oscillator. A frequency divider is provided for channel 1 to further optimize component size. At all frequencies, a 180° phase relationship between channels is maintained, reducing voltage ripple and component size. A clock output is available for synchronizing multiple regulators.Minimum input to output voltage ratios are improved by allowing the switch to stay on through multiple clock cycles only switching off when the boost capacitor needs recharging. Independent channel operation can be programmed using the SHDN pin. Disabling both converters reduces the total quiescent current to <10μA.The LT3692A is an improved version of the LT3692 with reduced minimum on-time.Min On-TimeFeaturesPackageLT3692180ns-5 × 5 QFN-32LT3692A140nsProgrammable Shutdown UVLOTSSOP-38E, 5 × 5 QFN-32ApplicationsAutomotive SuppliesDistributed Supply Regulation
