The LX1673 is a highly integrated power supply controller IC featuring one net PWM switching
regulator stage with an additional onboard linear
regulator driver.
With several switching frequencies available (up to 900kHz) the LX1673 can be optimized for both cost and PCB space.
Utilizing external compensation, a wide selection of external components can be chosen for use in any application while maintaining stable operation.
The LX1673 incorporates a fully programmable soft-start and power sequence capabilities.
The LDO and PWM have independent enable pins.
