The XL3842 from Xinluda is a high-performance, fixed-frequency current-mode PWM controller intended for off-line and DC-to-DC switching power supply designs that require few external components. Belonging to the widely adopted UC3842-style controller family, the XL3842 integrates a precision oscillator, error amplifier, current-sensing comparator, and a high-current totem-pole output stage suited to driving a power MOSFET directly. It is supplied in a compact SOP-8 surface-mount package.
Like other devices in this proven architecture, the XL3842 implements cycle-by-cycle current limiting through a latching PWM comparator and includes under-voltage lockout (UVLO) with hysteresis plus over-current protection, helping deliver robust, well-regulated power conversion in flyback, forward, and buck topologies. As a 3842-type variant, it uses higher UVLO thresholds (approximately 16V turn-on / 10V turn-off) and supports a high maximum duty cycle.
The XL3842 is a regional-market current-mode PWM controller with limited authorized-distributor coverage, which can make it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and optocouplers. Our team can locate the XL3842 and equivalent UC3842-family controllers, verify authenticity, and ship globally to keep your production line moving.
Because the XL3842 is offered on a request-for-quote basis, simply submit an RFQ with your target quantity and required date code, and our sourcing specialists will respond with current availability and pricing. Whether you need a single reel for a prototype or volume quantities for a production run, Pacific Component Xchange provides reliable access to hard-to-find components backed by quality screening and worldwide logistics.
The XL3842 is a high-performance, fixed-frequency current-mode PWM controller from Xinluda, supplied in an SOP-8 package. It belongs to the UC3842-style controller family used in off-line and DC-to-DC switching power supplies.
The XL3842 is a UC3842-type current-mode PWM controller, sharing the same widely adopted control architecture and SOP-8 pin layout common to the 384x controller family. As a 3842-type variant it uses higher UVLO thresholds (around 16V on / 10V off). Designers should always confirm exact electrical thresholds against the XL3842 datasheet before substituting in a specific design.
The XL3842 is offered in a compact SOP-8 surface-mount package.
Per distributor data, key specifications include a 12V to 28V supply range, 1A output drive current, 250 kHz switching frequency, 96% maximum duty cycle, 800 mW power dissipation, and an operating temperature range of 0u00b0C to +70u00b0C. It also features under-voltage lockout with hysteresis and over-current protection.
