LOW VOLTAGE STEP-UP
DC-DC CONVERTER
SC1633
January 29, 1998
Note:
(1) Add suffix ‘TR’ for tape and reel.
FEATURES
High efficiency 87%
Power-saving shutdown mode (7μA typical)
Internal 0.8A switch
120kHz switching rate
Adjustable switch current limit
On-chip low battery detector
DESCRIPTION
The SC1633 is a high efficiency step up DC-DC
converter. Only four external components are required
to deliver a fixed voltage of 3V, 3.3V, or 5V. Efficiency
beyond 83% can be easily achieved at 70mA load with
2.2V to 3V input voltages.
A logic-controlled shutdown mode is provided for
power saving. Switch current limit can be programmed
with a resistor. The low battery detector can be
configured as a linear regulator or a burst mode
controller providing extremely low supply current
operation.
A switching rate of 120kHz reduces the inductor size -
inductors of 47μH to 150μH inductance are
recommended for most applications.
