LTM8049EY#PBF

LINEAR TECHNOLOGY  LTM8049EY#PBF  DC/DC Inverting, SEPIC Adjustable Converter, POL, 2.5 MHz, 2.5 V to 24 V out, 1 A, BGA-77 新

The is a dual SEPIC or inverting µModule DC to DC converter in 77 pin BGA package. It contains two stand alone switching DC to DC converters. Either one may be configured as a SEPIC single ended primary inductance converter or inverting power supply simply by tying VOUTN or VOUTP to GND respectively. Each of the two outputs can be easily configured as a SEPIC or inverting converter by simply grounding the appropriate output rail. The LTM8049 includes power devices, inductors, control circuitry and passive components. All that is needed to complete design are input and output caps and small resistors to set the output voltages and switching frequency. Other components may be used to control the soft start and undervoltage lockout. It is typically used in battery powered regulator, local negative voltage regulator and low noise amplifier power.
