SC196A
1.5A Synchronous Buck Converter
with Integrated Power Devices
POWER MANAGEMENT
Description
November 2, 2006
Typical Application Circuit
Applications
The SC96A is a synchronous step-down converter with
integrated power devices. The SC96A is designed for
single-cell Li-Ion battery applications but can also be used
in fixed 3.3V or 5V applications. The switching frequency
is nominally set to MHz, allowing the use of small
inductors and capacitors. The maximum current rating of
the internal MOSFET switches allows a DC output current
of 1.5A.
Four programable output voltages
1.00V/1.05V/1.20V/
1.80V are available. See SC196 with external feedback
for other output voltage settings.
The SC196A has a flexible clocking methodology that
allows it to be synchronized to an external oscillator or
controlled by the internal oscillator. The device can
operate in either forced PWM mode or in PSAVE mode. If
PSAVE mode is enabled, the part will automatically enter
PFM at light loads to maintain maximum efficiency across
the full load range.
For noise sensitive applications, PSAVE mode can be
disabled by synchronizing to an external oscillator or
pulling the SYNC/PWM pin high. Shutdown turns off all
the control circuitry to achieve a typical shutdown current
of 0.μA.
