MCP1256/7/8/9 Regulated 3.3V, Low-Ripple
Charge Pump with Low-Operating Current
Sleep Mode or Bypass Mode
The MCP1256, MCP1257, MCP1258 and MCP1259
are inductorless, positive regulated charge pump
DC/DC converters. The devices generate a regulated 3.3V
output voltage from a 1.8V to 3.6V input. The devices are
specifically designed for applications operating from 2-cell
alkaline, Ni-Cd, or Ni-MH batteries or by one primary lithium
MnO2 (or similar) coin cell battery.
The MCP1256, MCP1257, MCP1258 and MCP1259 provide
high efficiency by automatically switching between 1.5x
and 2x boost operation. In addition, at light output loads,
the MCP1256 and MCP1257 can be placed in a Sleep
mode, lowering the quiescent current while maintaining
the regulated output voltage. Alternatively, the MCP1258
and MCP1259 provide a Bypass feature connecting the
input voltage to the output. This allows for real-time clocks,
microcontrollers or other system devices to remain biased
with virtually no current being consumed by the MCP1258
or MPC1259. In normal operation, the output voltage ripple
is below 20 mVPP at load currents up to 100 mA. Normal
operation occurs at a fixed switching frequency of 650 kHz,
avoiding interference with sensitive IF bands.
The MCP1256 and MCP1258 feature a power-good output
that can be used to detect out-of-regulation conditions. The
MCP1257 and MCP1259 feature a low battery indication
that issues a warning if the input voltage drops below a
preset voltage threshold.

MCP125
MCP1259
Extremely low supply current and few external parts
(4 capacitors) make these devices ideal for small, battery
powered applications. A Shutdown mode is also provided for
further power reduction. The devices incorporate thermal and
short-circuit protection. Two packages are offered: 10-pin
MSOP and 10-pin 3x3 DFN. The devices are completely
characterized over the junction temperature range of -40°C
to +125°C.
