MCP16311/2

30V Input, 1A Output, High-Efficiency,

Integrated Synchronous Switch Step-Down Regulator

Features

General Description

• Up to 95% Efficiency

The MCP16311/2 is a compact, high-efficiency, fixed

frequency, synchronous step-down DC-DC converter in

an 8-pin MSOP, or 2 x 3 TDFN package that operates

from input voltage sources up to 30V. Integrated

features include a high-side and a low-side switch, fixed

frequency peak current mode control, internal

compensation, peak current limit and overtemperature

protection. The MCP16311/2 provides all the active

functions for local DC-DC conversion, with fast transient

response and accurate regulation.

• Input Voltage Range: 4.4V to 30V

• 1A Output Current Capability

• Output Voltage Range: 2.0V to 24V

• Qualification: AEC-Q100 Rev. G, Grade 1 (-40°C

to 125°C)

• Integrated N-Channel High-Side and Low-Side

Switches:

- 170 m, Low Side

- 300 m, High Side

• Stable Reference Voltage: 0.8V

High converter efficiency is achieved by integrating the

current-limited, low-resistance, high-speed high-side

and low-side switches and associated drive circuitry.

The MCP16311 is capable of running in PWM/PFM

mode. It switches in PFM mode for light load

conditions and for large buck conversion ratios. This

results in a higher efficiency over all load ranges. The

MCP16312 runs in PWM-only mode, and is

recommended for noise-sensitive applications.

• Automatic Pulse Frequency Modulation/Pulse-

Width Modulation (PFM/PWM) Operation

(MCP16311):

- PFM Operation Disabled (MCP16312)

- PWM Operation: 500 kHz

• Low Device Shutdown Current: 3 µA typical

• Low Device Quiescent Current:

- 44 µA (non-switching, PFM Mode)

• Internal Compensation

The MCP16311/2 can supply up to 1A of continuous

current while regulating the output voltage from 2V to

12V. An integrated, high-performance peak current

mode architecture keeps the output voltage tightly

regulated, even during input voltage steps and output

current transient conditions common in power systems.

• Internal Soft-Start: 300 µs (EN low-to-high)

• Peak Current Mode Control

• Cycle-by-Cycle Peak Current Limit

• Undervoltage Lockout (UVLO):

- 4.1V typical to start

The EN input is used to turn the device on and off.

While off, only a few micro amps of current are

consumed from the input.

- 3.6V typical to stop

• Overtemperature Protection

• Thermal Shutdown:

Output voltage is set with an external resistor divider.

The MCP16311/2 is offered in small MSOP-8 and 2 x 3

TDFN surface mount packages.

- +150°C

- +25°C Hysteresis
