Linear Technology has announced the LTC3260 and LTC3261 high-voltage charge pumps. The LTC3261 is an inverting charge pump that can deliver up to 100 mA of output current.
The LTC3260 has the same charge pump as the LTC3261, but also includes both positive and negative LDO regulators that can source up to 50 mA output current each. The negative LDO post regulator is powered from the inverting charge pump output. The positive and negative LDO output voltages can be adjusted down to 1,2 V and -1,2 V, respectively, using external resistor dividers.
Both devices operate over a wide 4,5 V to 32 V input voltage range. Their internal charge pumps function in either low-quiescent-current burst mode or low-noise, constant-frequency mode at up to 88% efficiency.
In burst mode operation the charge pump output regulates to –0,94 · VIN. In this mode, the LTC3261 draws only 60 A quiescent current, while the LTC3260 draws only 100 A with both LDOs enabled.
Constant-frequency operation offers low input and output ripple; in this mode the charge pump produces an output equal to –VIN and operates at a fixed 500 kHz or to a programmed value between 50 kHz and 500 kHz using an external resistor.
Other IC features include low external parts count with ceramic capacitor stability, soft-start circuitry to prevent excessive current flow during startup, plus short circuit and thermal protection. The chips are well suited for a variety of applications such as low-noise bipolar/inverting supplies from a high-voltage input, industrial/instrumentation low-noise bias generators, portable medical equipment and automotive infotainment systems.
The LTC3260 is available in a low-profile (0,75 mm) 3 x 4 mm 14-lead DFN package and a 16-lead MSOP package, both with a backside thermal pad. The LTC3261 is available in a 12-lead MSOP package with backside thermal pad. For both devices, the E- and I-grade operating junction temperature is
