UMW TP4056 is a high-performance single-cell Li-ion battery linear charger IC utilising a constant current/constant voltage (CC/CV) charging architecture, designed for compact portable products powered by USB or adapter supplies. Supporting an input voltage range of 4V to 6.5V, the TP4056 fixes the charge termination voltage at 4.2V with an externally programmable charge current, and enters a low-power sleep state drawing less than 1µA battery leakage when the input is disconnected. A standby quiescent current of just 35µA (I_q) and support for 0V battery charging make the UMW TP4056 particularly well suited to deeply discharged cell recovery in power banks, wearables, and IoT devices. ABL Semi supplies the UMW TP4056 in an ESOP-8 package with flexible MOQ and 100% authentic, factory-original stock.

The UMW XL1509 is a 150kHz fixed-frequency PWM buck (step-down) DC/DC converter IC capable of delivering 2A continuous output current with high efficiency, low output ripple, and excellent line and load regulation across a wide input voltage range of up to 45V. Available in fixed output versions of 3.3V, 5V, and 12V as well as an adjustable (ADJ) version, the XL1509 integrates internal frequency compensation, a fixed-frequency oscillator, and an enable function — minimising external component count and simplifying PCB design significantly. A built-in two-stage overcurrent protection reduces switching frequency from 150kHz to 50kHz under sustained overload conditions, protecting the converter and downstream load. The PWM duty ratio is adjustable from 0% to 100%. ABL Semi supplies the UMW XL1509 in SOP-8 and ESOP-8 packages with flexible MOQ and pin-to-pin compatibility to the XL4005 and LM2596 buck regulator series.

The NCE XJNG2103 is a 200V high-voltage, high-speed half-bridge gate driver IC with dependent high-side and low-side referenced output channels, built on proprietary HVIC and latch-immune CMOS technology for ruggedised monolithic construction in demanding motor drive and power conversion applications. The floating channel supports bootstrap operation fully up to +200V, driving an N-channel MOSFET in the high-side configuration, while both channels deliver a symmetric 1A source (I_OH) and 1A sink (I_OL) peak output current with rise and fall times of 50ns and 40ns respectively. Operating from a gate drive supply of 9V to 20V with a quiescent current of just 160µA, the XJNG2103 accepts 3.3V, CMOS, and LSTTL logic inputs and is tolerant to negative transient voltages. ABL Semi supplies the XJNG2103 as a 100% authentic NCE product in SOIC-8, with flexible MOQ and pin-to-pin compatibility to the Infineon IR2103 series.
