SGM6611C

12.6V, 7A Fully-Integrated

Synchronous Boost Converter

GENERAL DESCRIPTION

FEATURES

The SGM6611C is a fully-integrated synchronous Boost

converter. The 2.7V to 12V operating input voltage is

suitable for single-cell or two-cell Li-Ion/Polymer

batteries. This device is capable of providing 7A

continuous switch current and an output voltage range

of 4.5V to 12.6V.

● 2.7V to 12V Input Voltage Range

● 4.5V to 12.6V Output Voltage Range

● Up to 90% Efficiency

(V_IN= 3.3V, V_OUT= 9V and I_OUT= 1.5A)

● Adjustable Peak Current Limit up to 9.5A for

High Pulse Current

The SGM6611C has two operation modes, the pulse

width modulation (PWM) mode and pulse frequency

modulation (PFM). The PWM mode is applied at

moderate to heavy load. The PFM mode is applied at

light load to improve the efficiency. The protection

features include output over-voltage protection at 13.2V,

cycle-by-cycle over-current protection and thermal

shutdown. The device also involves the functions of

4ms built-in soft-start and adjustable switch peak

current limit.

● 1.1MHz Fixed Switching Frequency (PWM Mode)

● 4ms Built-in Soft-Start

● PFM Operation Mode at Light Load

● 13.2V Internal Output Over-Voltage Protection

● Cycle-by-Cycle Over-Current Protection

● Thermal Shutdown

● Available in a Green TQFN-2×2.5-11L Package

APPLICATIONS

The SGM6611C is available in a Green TQFN-2×2.5-

11L package.
