MCP1256/7/8/9

Regulated 3.3V, Low-Ripple Charge Pump with Low-

Operating Current SLEEP Mode or BYPASS Mode

Features

Description

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.

• Inductorless 1.5x, 2x Boost DC/DC Converter

• Output Voltage: 3.3V

• High Output Voltage Accuracy:

- ±3.0% (V_OUTFixed)

• Output Current Up To 100 mA

• 20 mV_PPOutput Voltage Ripple

• Thermal Shutdown and Short Circuit Protection

• Uses Small Ceramic Capacitors

• Switching Frequency: 650 kHz

• Low-Power SLEEP Mode: MCP1256/7

• BYPASS Mode: MCP1258/9

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

• Low-Power Shutdown Mode: 0.1 μA (Typical)

• Shutdown Input Compatible with 1.8V Logic

• V_INRange: 1.8V to 3.6V

output.

This

allows

for

real-time

clocks,

• Soft-Start Circuitry to Minimize Inrush Current

• Temperature Range: -40°C to +125°C

• Packaging:

microcontrollers or other system devices to remain

biased with virtually no current being consumed by the

MCP1258 or MPC1259.

- 10-Pin, 3 mm x 3 mm DFN

In normal operation, the output voltage ripple is below

20 mV_PPat load currents up to 100 mA. Normal opera-

tion occurs at a fixed switching frequency of 650 kHz,

avoiding interference with sensitive IF bands.

- 10-Pin, MSOP

Applications

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.

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.
