MCP1641X

Low I_QBoost Converter with Programmable Low Battery, UVLO and

Automatic Input-to-Output Bypass Operation

Features

Description

• Input Voltage Range: 0.8V (after Start-up) 

to 5.25V

The MCP1641X Step-up DC-DC Converters family

provides an automatic input-to-output voltage bypass

operation, which helps optimize battery utilization and

achieve high efficiency, while the nominal voltage of

fresh batteries remains in the same range with the con-

verter’s output value. The MCP1641X can be powered

by either single-cell, two-cell alkaline/NiMH batteries or

single-cell Li-Ion/Li-Polymer batteries.

• Low Device Quiescent Current: 5 µA (typical),

PFM Mode (not switching)

• Up to 96% Efficiency

• 1A Typical Inductor Peak Current Limit:

- I_OUT> 170 mA at 2V V_OUT, 1.2V V_IN

- I_OUT> 200 mA at 3.3V V_OUT, 1.5V V_IN

- I_OUT> 600 mA at 5.0V V_OUT, 3.6V V_IN

• Adjustable Output Voltage Range

• Automatic Input-to-Output Bypass Operation

• Selectable Switching Mode:

low-voltage designed architecture allows the

regulator to start up without high inrush current or

output voltage overshoot from a low input voltage. The

start-up voltage is easily programmed by a resistive

divider connected to the UVLO pin. If the resistive

divider is not used, the default start-up voltage is 0.85V.

The 0.8V built-in UVLO_STOPhelps prevent deep dis-

charge of the alkaline battery, which can cause battery

leakage. An open-drain Low Battery Output (LBO) pin

warns the user to replace the battery if the input voltage

ramps down to the programmed UVLO_STARTvalue.

- PWM operation: 500 kHz (MCP16412/4/6/8)

- Automatic PFM/PWM operation

(MCP16411/3/5/7)

• Programmable Undervoltage Lockout (UVLO)

• Programmable Low Battery Output (LBO)

• Selectable Status Indicator:

The MCP1641X family introduces an additional safety

- Power Good and Die Overtemperature 

output (MCP16411/2/3/4)

feature to a low-voltage boost converter: Over-

temperature Output. Devices, such as personal care

products, Bluetooth headsets or toys, will benefit from

the combined Power Good and Die Overtemperature

(PGT) output, which flags a warning signal when the out-

• Inrush Current Limiting and Internal Soft Start

• Low Noise, Anti-Ringing Control

• Thermal Shutdown

exceeds the +75°C (typical).

Both functions are

implemented in the MCP16411/2/3/4 devices (on the

same pin, PGT), while the MCP16415/6/7/8 devices

have only the Power Good option.

• Selectable Shutdown States:

- Output discharge option (MCP16411/2/5/6)

Note 1: Factory programmable from +55C to

+85C, at +10C increments, by customer

request.

- Input-to-output bypass option

(MCP16413/4/7/8)

• Shutdown Current: 2.3 µA (typical)
