DESCRIPTION
The TPS6024x is a switched capacitor voltage
converter, ideally suited for VCO and PLL applications
that require low noise and tight tolerances. Its dual-cap
design uses four ceramic capacitors to provide ultralow
output ripple yet high efficiency, while eliminating the
need for inefficient linear regulators.
A wide input supply voltage range of 2.7 V to 5.5 V
makes the TPS6024x ideal for lithium-based battery
applications. The TPS60240/2/3 operates down to
1.8 V, supporting a 3.3-V, 2.7-V, 3-V output from
two-cell, nickel- or alkaline-based chemistries. 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 converter’s shutdown mode conserves battery
energy.
