In SEPIC configuration, the regulated output voltage can be above, below, or equal to the input voltage. The device integrates power devices, inductors, control circuitry, and passive components into a single 40-lead BGA package. Operating from 2.8V to 18V input, it delivers up to 700mA output current at +\/-2.5V or 375mA at +\/-15V. The switching frequency is selectable from 200kHz to 2MHz via an external resistor. Programmable soft-start and user-configurable UVLO provide additional design flexibility. Only input\/output capacitors and small setting resistors are needed to complete the design.","working_principle":"The LTM8045IY#PBF operates as a current-mode controlled SEPIC or inverting converter with integrated magnetics. Key subsystems include: (1) Current-Mode PWM Controller - regulates the output voltage by comparing the error amplifier output with the switch current; (2) Integrated Power MOSFETs - both high-side and low-side switches are integrated; (3) Integrated Inductor - a custom power inductor is encapsulated within the BGA package; (4) Feedback Network - an external resistor divider sets the output voltage; (5) Configuration Logic - grounding VOUT+ configures inverting mode, grounding VOUT- configures SEPIC mode; (6) Soft-Start - an external capacitor programs the startup ramp rate.","pin_description":"
