HT7886 -100V输入，3.5A开关限流降压变换器
The HT7886 is a high-voltage, step-down, switching
regulator that delivers up to 2A of continuous current to the
load. It integrates a high-side, high-voltage, power
MOSFET with a current limit of 3.5A (HT7886) or 4.2A
(HT7886H), typically. The wide 5V to 100V input range
accommodates a variety of step-down applications, making
it ideal for automotive, industry, and lighting applications.
Hysteretic voltage-mode control is employed for very fast
response.
The switching frequency can be up to 1MHz, allowing for
small component size. Thermal shutdown and short-circuit
protection (SCP) provide reliable and fault-tolerant
operations. A 200µA quiescent current allows the HT7886
to be used in battery-powered applications.
The HT7886 is available in ESOP8 package.
