MCP1603/B/L

2.0 MHz, 500 mA Synchronous Buck Regulator

General Description

Features

• Over 90% Typical Efficiency

• Output Current Up To 500 mA

The MCP1603/B/L is a high-efficiency, fully-integrated

500 mA synchronous buck regulator whose 2.7V to

5.5V input voltage range makes it ideally suited for

applications powered from 1-cell Li-Ion or 2-cell/3-cell

NiMH/NiCd batteries.

• Low PFM Quiescent Current = 45 µA, typical

(MCP1603/L)

• Low Shutdown Current = 0.1 µA, typical

• Adjustable Output Voltage:

At heavy loads, the MCP1603/B/L operates in the

2.0 MHz fixed frequency pulse-width modulation

(PWM) mode, which provides a low noise, low-output

ripple, small-size solution. When the load is reduced to

light levels, the MCP1603/L automatically changes

operation to a Pulse Frequency Modulation (PFM)

mode to minimize quiescent current draw from the

battery. No intervention is necessary for a smooth

transition from one mode to another. These two modes

of operation allow the MCP1603/L to achieve the

highest efficiency over the entire operating current

range.

- 0.8V to 4.5V

• Fixed Output Voltage:

- 1.2V, 1.5V, 1.8V, 2.5V, 3.3V (MCP1603/L)

- 1.8V, 3.3V (MCP1603B)

• 2.0 MHz Fixed-Frequency PWM (Heavy Load)

• Automatic PWM-to-PFM Mode Transition

(MCP1603/L)

• PWM Mode Only Option (MCP1603B)

• 100% Duty Cycle Operation

• Internally Compensated

The MCP1603B device disables the PFM mode

switching, and operates only in normal PWM mode

over the entire load range (without skipping).

MCP1603B is for applications that cannot tolerate the

low-frequency output ripple associated with PFM

switching.

• Undervoltage Lockout (UVLO)

• Overtemperature Protection

• Space Saving Packages:

- 5-LeadTSOT, TwoPinoutTypes(MCP1603/L)

- 8-Lead 2 x 3 DFN

The MCP1603/B/L family is available with either an

adjustable or fixed-output voltage. The available fixed

output voltage options for MCP1603/L are 1.2V, 1.5V,

1.8V, 2.5V and 3.3V, and for MCP1603B are 1.8 and

3.3V. When a fixed option is used, only three additional

small external components are needed to form a

complete solution. Couple this with the low profile,

small-foot print packages and the entire system

solution is achieved with minimal size.

Applications

• Cellular Telephones

• Portable Computers

• Organizers / PDAs

• USB Powered Devices

• Digital Cameras

• Portable Equipment

• +5V or +3.3V Distributed Systems

• Headsets

Additional protection features include: UVLO,

overtemperature and overcurrent protection.
