FAN48619UC50X Description

Short technical summary and product information.

The FAN48619UC50X is a low-power, PWM-only boost regulator designed by ON Semiconductor. It is engineered to deliver a stable, voltage-regulated output rail from single-cell Li-Ion batteries and advanced battery chemistries, maintaining regulation even below the minimum system battery voltage for output load currents up to 1000 mA.

 

Key electrical specifications include an input voltage range of 2.7V to 4.5V and a fixed output voltage of 5.0V. The device boasts a maximum load capability of 1A and operates at a switching frequency of 2.3MHz. It achieves high efficiency, up to 97%, and features internal synchronous rectification for improved performance. The regulator also includes true load disconnect and short-circuit protection.

 

Designed for battery-powered applications, the FAN48619UC50X is suitable for devices such as smartphones, tablets, and portable electronics. Its compact size and efficiency make it ideal for RF applications and NFC applications. The device requires only three external components: an inductor, an input capacitor, and an output capacitor.

 

The FAN48619UC50X is available in a 9-bump, 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP), measuring 1.215x1.215 mm. This surface-mount package is designed for space-constrained applications. The operating temperature range is -40°C to 85°C (TA).
