SGM6611

12.6V, 7A Fully-Integrated

Synchronous Boost Converter

GENERAL DESCRIPTION

FEATURES

The SGM6611 family includes the SGM6611A and the

● 2.7V to 12V Input Voltage Range

● 4.5V to 12.6V Output Voltage Range

● Up to 90% Efficiency

SGM6611B. The SGM6611 is

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. It also has an

adjustable switching frequency ranging from 200kHz to

2.2MHz.

(V_IN= 3.3V, V_OUT= 9V, I_OUT= 2A)

● Adjustable Peak Current Limit up to 9.5A for

High Pulse Current

● Adjustable Switching Frequency: 200kHz to 2.2MHz

● 4ms Built-in Soft-Start Time

● PFM Mode at Light Load (SGM6611A)

● Forced PWM Mode at Light Load (SGM6611B)

● 13.2V Internal Output Over-Voltage Protection

● Over-Current Protection

● Thermal Shutdown

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

The SGM6611 family has two operation modes, the

pulse width modulation (PWM) mode and pulse

frequency modulation (PFM). The SGM6611 family

adopts the PWM mode at moderate to heavy load. The

PFM mode is applied at light load by SGM6611A to

improve the efficiency. However, the SGM6611B still

adopts the PWM mode to prevent the device from low

switching frequency faults. 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.

APPLICATIONS

Portable POS Machine

Bluetooth Speaker

E-Cigarette

Fast-Charging Power Bank

The SGM6611A and SGM6611B are both available in a

Green TQFN-2×2.5-11L package.
