The SG1577A is a high-efficiency, voltage-mode, dualchannel, synchronous DC/DC PWM controller for two independent outputs. The two channels are operated out of phase. The internal reference voltage is trimmed to 0.7V±1.5%. It is connected to the error amplifier’s positive terminal for voltage feedback regulation.
The soft-start circuit ensures the output voltage can be gradually and smoothly increased from zero to its final regulated value. The soft-start pin can also be used for chip-enable function. When two soft-start pins are grounded, the chip is disabled and the total operation current can be reduced to under 0.7mA.
The fixed-frequency is programmable from 60kHz to 340kHz. The Over-Current Protection (OCP) level can be programmed by an external current sense resistor. It has two integrated sets of internal MOSFET drivers.
SG1577A is available in a 20-pin SOP package.

The FAN2560 is a linear low-dropout (LDO) regulator with a split-supply architecture. Separate bias and supply inputs allow bias to be taken directly from the battery, while the input is taken from a lower preregulated source. This allows a smaller differential voltage between input and output, which provides greater efficiency over a wider VBAT range.
The FAN2560 is available in a fixed-voltage output, 5-bump, WLCSP package.

The highly integrated SG6742HL/HR PWM controller provides several features to enhance the performance of flyback converters.
To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency at light-load conditions. To avoid acoustic-noise problems, the minimum PWM frequency is set above 22KHz. This green-mode function enables the power supply to meet international power conservation requirements. With the internal high-voltage startup circuitry, the power loss due to bleeding resistors is eliminated. To further reduce power consumption, SG6742HL/HR is manufactured using the BiCMOS process, which allows an operating current of 2.7mA.
SG6742HL/HR integrates a frequency-hopping function internally that helps reduce EMI emission of a power supply with minimum line filters. Its built-in synchronized slope compensation achieves stable peak-current-mode control. The proprietary, internal line compensation ensures constant output power limit over a wide AC input voltage range, from 90VAC to 264VAC.
SG6742HL/HR provides many protection functions. In addition to cycle-by-cycle current limiting, the internal open-loop protection circuit ensures safety should an open-loop or output short-circuit failure occur. PWM output is disabled until VDD drops below the UVLO lower limit, when the controller starts up again. As long as VDD exceeds ~25V, the internal OVP circuit is triggered.
SG6742HL/HR is available in an 8-pin SOP package.
