LTM8045IY#PBF

LTM®8045 is a µModule® (micromodule) DC/DC converter that can be configured as a SEPIC or inverting converter by simply grounding the appropriate output rail. In a SEPIC configuration the regulated output voltage can be above, below or equal to the input voltage. This includes power devices, inductors, control circuitry and passive components. All that is needed to complete the design are input and output capacitors, and small resistors to set the output voltage and switching frequency. Other components may be used to control the soft-start and undervoltage lockout. Typical applications are battery powered regulator, local negative voltage regulator, low noise amplifier power.

• SEPIC or inverting topology, programmable soft-start
• User configurable undervoltage lockout
• Input DC voltage range from 2.8 to 18V (TA=25°C. RUN=12V)
• Continuous output DC current is 0.7A maximum (VIN=12V, VOUT=2.5V or -2.5V)
• VIN quiescent current is 1µA maximum (VRUN=0V)
• Output RMS voltage ripple is 4mV typ (VIN=12V, VOUT=5V, IOUT=580mA, 100KHz to 4MHz)
• Switching frequency range from 1800 to 2200KHz (RT=45.3K, TA=25°C. RUN=12V)
• 40-lead BGA package
• Temperature rating range from -40°C to 125°C
