MIC23356 SHORT OVERVIEW
The MIC23356 device is a compact I
2
C programmable, high-efficiency, 3A continuous
current, synchronous step-down regulator. The Constant-ON-Time (COT) control
architecture with HyperLight Load™ (HLL) provides very high efficiency at light loads,
while still having ultra-fast transient response. The user can program, via the I

C
interface, various parameters, such as: output voltage, ON-time, soft start slope,
high-side current limit, HLL or Forced PWM mode of operation. The 2.4V to 5.5V input
voltage range, low shutdown and quiescent currents make the MIC23356 ideal for
single-cell, Li-Ion, battery-powered applications.
An open-drain Power Good (PG) output is provided to indicate when the output voltage
is within 9% of regulation and facilitates output voltage monitoring and sequencing.
When set in Shutdown mode (EN = GND), the current consumption of MIC23356 is
reduced to 1.5 µA (typical).
The MIC23356 is available in a thermally-efficient, 16-Lead 2.5 x 2.5 x 0.55 mm thin
MLF package, with an operating junction temperature range from -40°C to +125°C.
More detailed information regarding the capabilities of the MIC23356 are available in
the data sheet.
