Fully Integrated Step-Down Converters General Description The MAX20004/MAX20006/MAX20008 are small, synchronous buck converter devices with integrated high-side and
low-side MOSFETs. The device family can deliver up to
8A with input voltages from 3.5V to 36V, while using only
25μA quiescent current at no load. Voltage quality can be
monitored by observing the RESET signal. The devices can
operate in dropout by running at 98% duty cycle, making
them ideal for automotive applications.
The devices offer fixed output voltages of 5V and 3.3V,
along with the ability to program the output voltage between
1V and 10V. Frequency is resistor programmable from
220kHz to 2.2MHz. The devices offer a forced fixed-frequency PWM mode (FPWM) and skip mode with ultra-low
quiescent current. The devices can be factory programmed
to enable spread-spectrum switching to reduce EMI.
The MAX20004/MAX20006/MAX20008 are available in a
small, 3.5mm x 3.75mm, 17-pin FC2QFN package and use
very few external components. Applications ●● Point-of-Load (PoL) Applications in Automotive
