FAN5336

1.5MHz Boost Regulator with 33V Integrated FET Switch

Features

Description

■ 1.5MHz Switching Frequency

■ Low Noise

The FAN5336 is a high-efficiency, low-noise, fixed-fre-

quency PWM, current-mode, DC-DC boost regulator. It

is designed for small LCD bias supply and white LED

backlight supply applications. Depending on the applica-

tion, a FAN5336 regulator can output up to 33V at up to

50mA output current. With output voltage up to 21V, the

output current can be up to 100mA. FAN5336 can be

used for power conversion as low as 9V output voltage.

■ Adjustable Output Voltage

■ Up to 1.5A Peak Switch Current

■ Low Shutdown Current: <1µA

■ Cycle-by-Cycle Current Limit

■ Over-Voltage Protection at the Feedback Pin

■ Fixed-Frequency PWM Operation

■ Soft-Start Capability

A current-mode control loop has a fast transient

response that provides excellent load regulation within

0.2% of output voltage. The FAN5336 switches at fixed

1.5MHz frequency, allowing the use of small, low-cost

external components. Constant frequency switching

results in low input noise and small output capacitors.

FAN5336 provides cycle-by-cycle current limiting up to

1.5A peak current.

■ Internal Compensation

■ Thermal Shutdown

■ Excellent Load Regulation: 0.2%

■ Low Ripple

■ 6-Lead 3x3mm MLP

The FAN5336 may be used to drive a serial flash LED

with up to 100mA current at 21V for a maximum of

400ms on-time and 10% duty cycle.

Applications

■ Portable Displays

■ Mobile Phone / Smart Phone LED Backlights

■ Display Bias

A low-EMI mode reduces interference and radiated elec-

tromagnetic energy caused by the ringing of the inductor.

■ PDA, DVD, Camcorder Backlights

■ Pager and Cordless Phone Displays

■ Portable Medical Diagnostic Equipment

■ Remote Controls

Additional features include thermal shutdown, over-volt-

age protection, cycle-by-cycle current limit, low ripple,

and soft-start support.

The device is available in a 3x3mm 6-lead MLP, 0.8mm

thickness package.

■ MP3 or PMP or DSC Players

■ Serial Flash LED Drivers
