DESCRIPTION
The SC1630 is a DC-DC converter designed to drive
an external power switch for more flexibility, especially
in higher voltage and larger power applications.
Typically six components are required to set up a
step-up configuration easily achieving an efficiency
beyond 80%. A few more components are required to
set up a step down configuration delivering 4A load
current with 83% typical efficiency, 86% at 2A load,
and 300µA quiescent current.
The output voltage can be internally set to 5V or
externally set to an arbitrary value below breakdown
voltage of the power switch. Logic-controlled
shutdown mode is provided for power-saving. The low
battery detector can also be configured as a linear
regulator.
A 120kHz switching rate reduces the inductor size.
Inductors of 25µH to 50µH inductance are
recommended for most applications.
FEATURES
• Default +5V output voltage
• Adjustable output voltage with two resistors
• Power-saving shutdown mode (7µA typical)
• 120kHz switching rate
• On-chip low battery detector
