MIC94300 Evaluation Board
200mA Switch
with Ripple Blocker™ Technology
General Description
The MIC94300 is an integrated load switch that
incorporates Micrel’s Ripple Blocker™ active filter
technology. The MIC94300 provides high-frequency
ripple attenuation for applications where switching noise
cannot be tolerated by sensitive downstream circuits
such as in RF applications. The MIC94300 replaces a
high-side switch, large filtering inductor, and capacitors
to save board area.
The MIC94300 operates from an input voltage of 1.8V to
3.6V, allowing true load switching of low-voltage power
rails in any electronic device. The output voltage (V_OUT)
is set at a fixed drop from the input voltage.
Datasheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
Requirements
The MIC94300 evaluation board requires an input power
supply that is capable of delivering a minimum of 300mA
at a voltage range of 1.8V to 3.6V. The output load can
be either active or passive.
Precautions
The MIC94300 evaluation board does not have reverse
polarity protection. Applying a negative voltage to the
V_IN terminal may damage the device.
Getting Started
• Connect an External Supply to V_IN. Apply the
desired input voltage to the V_IN and ground terminal
of the evaluation board, paying careful attention to
polarity and supply voltage (1.8V ≤ V_IN ≤ 3.6V).
• Enable/Disable the MIC94300. The evaluation
board is supplied with 100kΩ pull-up resistor to V_IN
for default on state. To disable the output, simply
jumper the EN terminal to ground.
• Connect the Load. Connect the load to the V_OUT
terminal and the ground terminal. The load can be
either a passive (resistor) or active (electronic load).
Be sure to monitor the output voltage at the V_OUT
terminal.
