MIC2296
High Power Density 1.2A
Boost Regulator
General Description
The MIC2296 is a 600kHz, PWM dc/dc boost switching
regulator available in a 2mm x 2mm MLF
®
package option.
High power density is achieved with the MIC2296’s
internal 34V / 1.2A switch, allowing it to power large loads
in a tiny footprint. The MIC2296 is a version of the
MIC2295 1.2MHz, PWM dc/dc boost switching regulator,
that offers improved efficiency resulting from 600kHz
operation.
The MIC2296 implements constant frequency 600kHz
PWM current mode control. The MIC2296 offers internal
compensation that offers excellent transient response and
output regulation performance. The high frequency
operation saves board space by allowing small, low-profile
external components. The fixed frequency PWM scheme
also reduces spurious switching noise and ripple to the
input power source.
The MIC2296 is available in a low-profile Thin SOT23 5-
pin package and a 2mm x2mm 8-pin MLF
®
leadless
package. The 2mm x 2mm MLF
®
package option has an
output over-voltage protection feature.
The MIC2296 has an operating junction temperature range
of –40°C to +125°C
Features
2.5V to 10V input voltage range
Output voltage adjustable to 34V
1.2A switch current
600kHz PWM operation
Stable with small size ceramic capacitors
