The SC183C is a 2A synchronous step-down regulator
designed to operate with an input voltage range of 2.9 to
5.5 Volts. The device offers fifteen pre-determined outputs
voltages via four control pins programmable from 0.8 to
3.3 Volts. The control pins allow for on-the-fly voltage
changes, enabling system designers to implement
dynamic power savings. The SC183C is also capable of
adjusting output voltage via an external resistor divider.
The device operates with a fixed 2.5MHz oscillator fre-
quency, allowing the use of small surface mount external
components.
Connecting CTL0 — CTL3 to logic low forces the device
into shutdown mode reducing the supply current to less
than 1μA. Connecting any of the control pins to logic
high enables the converter and sets the output voltage
according to Table 1. Other features include under-
voltage lockout, soft-start to limit in-rush current, and
over-temperature protection.
The SC183C is available in a thermally-enhanced, 3mm x
