High Current Pfm Boost Converter Corporation

The LX1732 is a compact, high efficiency, Step-up DC-DC boost Regulator implemented in a BiCMOS process technology. This device features variable frequency operation and a built in N-channel MOSFET power Switch for optimal functioning in low voltage portable systems. Start-up operation is guaranteed from 1.1V inputs (at light load) and the input voltage CAN be as low as 0.7V after start-up. This attribute allows the LX1732 to operate in an extended power- savings mode, supplying (data) critical system components, even after battery capacity no longer supports normal operation. The output voltage programming range of 2.2V to 5V, requires only two external resistors via the feedback pin (see Figure 1.0). Output load currents of up to 200mA are achievable and the internal MOSFET is capable of switching up to a 1A current limit. Quiescent current during operation is 200A (max) and in shutdown- mode drops to a mere 1A thus maximizing overall battery life- time. The LX1732 features a low battery-detect circuitry that alerts system Power Management of low input voltages thus allowing portable systems to enter a power- savings mode (e.g., to protect data) By Microsemi Corporation
