General Description

The Micrel MIC2295 is a small 1.2MHz constant

frequency PWM DC/DC step-up switching regulator.

The MIC2295 is available in either a thin SOT-23 or a

2mm x 2mm MLF ® package. High power densities, in

a very small size, are achieved using its internal

34V/1.2A switch.

Requirements

The MIC2295 evaluation board requires an input

power source that is able to deliver greater than 1.2A

at 2.5V.

Precautions

The evaluation board does not have reverse polarity

protection. Applying a negative voltage to the VIN

terminal may damage the device.

The MIC2295 evaluation board is tailored for a Li-ion

range input supply voltage. The MIC2295 evaluation

board should not exceed 6.3V on the input unless the

standard input capacitor is replaced with a higher

rated input capacitor.

Getting Started

1. Connect an external supply to V IN. Apply

desired input voltage to the V IN (J1) and

ground (J2 and J5) terminals of the evaluation

board, paying careful attention to polarity and

supply voltage (2.5V≤V IN≤6.3V). An ammeter

may be placed between the input supply and

the VIN terminal to the evaluation board.

Ensure that the supply voltage is monitored at

the VIN terminal. The ammeter and/or power

lead resistance can reduce the voltage

supplied to the input. A 10uF input capacitor is

used on the evaluation board to help

compensate for long cables used in most lab

settings.

2. Connect the load to the V OUT (J4) and

ground terminals. The load can be either

passive (resistor) or active (electronic load).

An ammeter can be placed between the load

and the V OUT terminal. The default output

voltage is set to 12V. This can be adjusted by

changing the feedback resistors.

3. Enabling the MIC2295. Apply a 1.5V or

greater voltage to the enable (J3) terminal.

Output Voltage

The output voltage on the MIC2295 evaluation board

is adjustable. The output voltage is controlled by the

feedback resistors (R1 and R2) and can be calculated

as follows:

VOUT = 1.24V + 1

( )

The evaluation board is initially adjusted to 12V, but

can easily be modified by removing R1 and replacing

it with the value that yields the desired output voltage.

(Caution: Do not power up the MIC2295 SOT-23

version with R1 removed. The SOT-23 version does

not have over-voltage protection thus the output

voltage will steadily increase until the device self-

destructs).

VOUT

1.24V

Ensure the output voltage selected does not exceed

the 25V rating of the output capacitor. When output

voltages greater than 25V are desired, the output

capacitor should be replaced with one rated greater

than the maximum output voltage. The following

chart defines the minimum output capacitor value

recommended for different output voltages.

Output Voltage Recommended Output Capacitor

<6V 22uF

<16V 10uF

<34V 4.7uF
