BH 15RB1WGUT-E2 Application Field and Working Principle

The BH 15RB1WGUT-E2 is a linear-regulating pulse width modulator (PWM) voltage regulator, a member of the Class 2 Precision Battery Charger IC family manufactured by BH Electronics. The wide input voltage range of the BH 15RB1WGUT-E2 coupled with the ability to select PWM or linear-regulating output options make it an excellent choice for a wide range of applications including automotive, medical, industrial, and consumer electronics.

The BH 15RB1WGUT-E2 can be used to control the output voltage of any linear, pulse-width-modulated DC power supply. It is able to precisely regulate its output voltage without inductor-based linear voltage regulator components which are more expensive, difficult to implement, and comparatively inefficient.

The BH 15RB1WGUT-E2 is based on the company’s patented PWM modulation circuitry. It includes an integrated low-dropout regulator, temperature-sensing accuracy, current-mode control, and cycle-by-cycle current limiting. The control of the device output is achieved by adjusting the duty cycle of an immobilized PWM control signal.

One of the main advantages of the BH 15RB1WGUT-E2 is its high performance in the presence of large transient changes in the load current. Thanks to its patented PWM modulation circuitry, the BH15RB1WGUT-E2 offers enhanced output voltage regulation compared to linear voltage regulators which employ pulse-skipping or slope compensation techniques. The BH15RB1WGUT-E2 also offers excellent load response to differential voltage drop changes.

The BH 15RB1WGUT-E2 has a wide input voltage range of up to 40 volts, making it suitable for use in a variety of different applications. It also provides a number of additional features to help simplify the design of voltage regulators, including high-speed synchronous rectification, active power-good functionality, an adjustable feedback capacitor, and an over-temperature protection circuit.

The BH 15RB1WGUT-E2 is designed to operate in either normal or low-noise mode, allowing users to select the mode most suitable for their application. In normal mode, the load transient response is optimized for high-load current applications, while in low-noise mode, the BH 15RB1WGUT-E2 can effectively reduce switch noise and improve output voltage regulation. The optimum balance between load transient response and low-noise operation is achieved by setting the PWM frequency between 20 and 200 kHz.

The BH 15RB1WGUT-E2 is an excellent choice for precision battery charging applications due to its high accuracy, low noise operation, wide input voltage range, and its ability to efficiently regulate output voltage. The device is also suitable for other applications, such as DC/DC converters, AC/DC power supplies, and automotive electronic systems.
