Description
SL6802 is a triple DC-DC converter designed to drive AMOLED display panel requiring 3 supply rails. It integrates an 200mA step-up converter VPOS, an 200mA inverting converter VNEG and an 20mA auxiliary LDO AVDD.
The device is particularly suitable for battery operated products, in which the major concern is the overall system efficiency. The digital control allows programming the VNEG in digital steps.
Excellent line and load regulation, soft start with controlled inrush current limit, thermal shutdown and short circuit protection are also integrated.

LM2596SX/LM2596HV is a fixed frequency PWM DCDC voltage stabilizing power converter with fixed frequency of 150KHz. With the 3A output current driving ability, it has characteristics such as high efficiency, low ripple wave, high linear adjustment rate and load regulation. With the PWM modulation mode, the chip can adjust the linear ranges of the duty ratio of 0-100%. LM2596SX/LM2596HV has a built-in fixed frequency oscillator and a frequency compensation module, withsimple use, and only a small number of external components and parts are needed. In addition, the chip has built-in functions such as enabling, over-temperature protection, over-current protection and stimulation over-current protection with the hysteresis function. In condition of secondary over-current protection, the built-in down-conversion function can reduce the working frequency from 150KHz to 50KHz.

SL8366 is a PWM buck DC/DC converter integrating a synchronous switch, housed in an ESOP-8 package with exposed pads. It features an adjustable output voltage with a reference feedback voltage of 600mV and operates over an input voltage range of 4.75V to 42V, making it suitable for a wide range of applications, designed for harsh automotive environments.
The voltage-to-frequency converter provides an output pulse sequence that is accurately proportional to the applied input voltage. The LM331 can convert output frequencies from 1Hz to 100KHz when powered as low as 4V. It is well-suited for use in simple, low-cost circuits for applications such as analog-to-digital conversion, long-term integration, linear frequency modulation or demodulation, frequency-to-voltage conversion, and many other functions.
The LM2596/LM2596HV is a PWM DC-DC buck regulator with a fixed frequency of 150 kHz.It features a 3A output current capability, high efficiency, low ripple, and excellent linearity in both line and load regulation. The chip uses PWM modulation, allowing the duty cycle to be adjusted linearly in the range of 0-100%. The LM2596/LM2596HV integrates a fixed-frequency oscillator and a frequency compensation module, making it very easy to use with minimal external components. Additionally, it includes several built-in protection features, such as enable with hysteresis, over-temperature protection, over-current protection, and latch-off over-current protection. In the event of secondary over-current protection,the chip automatically reduces the operating frequency from 150 kHz to 50 kHz.
SL4139 is a DC/DC boost converter that provides precise constant current drive for multiple LEDs. With a fixed switching frequency of 1MHz, SL4139 can be paired with small external ceramic capacitors and inductors. Adjustable current, set by external resistor R1, allows SL4139 to drive series-connected LEDs. It is suitable for driving LEDs of the same type, with up to 9 white LEDs in series or a maximum driving voltage of 32V. LED brightness can be adjusted using a DC voltage, logic signal, or pulse width modulation (PWM). The shutdown control pin (SHDN) enables the device to operate in ultra-low static current standby mode.In addition to thermal protection and overcurrent limiting, SL4139 enters ultra-low power mode in the event of LED open-circuit faults. The chip is packaged in a small SOT23-5 form factor.
