SC190 Description
The SC190 is a synchronous step-down converter with integrated power devices and an integrated front-end LDO to minimize input supply ripple. Output voltage is programmable using two control bits, eliminating the need for feedback resistors tied to the output. The device is offered in four distinct variants with each variant providing four fixed output voltage options to choose from.
SC190 Key Features
- Less than 1mV Supply Ripple
- Output Voltage Regulated by Either the Switching
- The SC190’s flexible clocking scheme allows it to be
- synchronized to an external oscillator or controlled by the
- internal oscillator. The 1MHz switching frequency allows
- the use of small inductors and capacitors
- The internal MOSFET switches provide peak current greater than 500mA to achieve a DC output of at least 300mA. Shutdown
