3 Description
The TPS6024x devices are a family of switched
capacitor voltage converters, ideally suited for voltage-controlled oscillator (VCO) and phase-locked
loop (PLL) applications that require low noise and
tight tolerances. Its dual-cap design uses four
ceramic capacitors to provide ultra-low output ripple
with high efficiency, while eliminating the need for
inefficient linear regulators.
The TPS6024x devices operate down to 1.8 V,
supporting a 3.3-V, 2.7-V, 3-V output from two-cell,
nickel- or alkaline-based chemistries, whereas the
TPS60241 works with 2.7-V to 5.5-V input voltage
providing a 5-V output. The devices work equally well
for low EMI DC–DC step-up conversion without the need for an inductor. The high switching frequency
(typical 160 kHz) promotes the use of small surface•
mount capacitors, saving board space. The shutdown
mode of the converter conserves battery energy.
The devices are thermally protected and current•
limited for reliable operation even under persisting
fault conditions. Normal quiescent current (ground pin current) is only 250 μA, and typically 0.1 μA in
shutdown mode. The TPS6024x devices come in a
thin, 8-pin VSSOP package with a component height
of only 1.1 mm.
