Automotive Boost Regulator with 4A Integrated Switch

The ISL78219 is a high frequency, high efficiency

current-mode control non-synchronous step-up voltage

regulator operated at a constant PWM switching

frequency. It has an internal 4.0A, 120mΩ low-side

MOSFET and can deliver high output current and

efficiency over 90%. The selectable 640kHz and

1.22MHz switching frequencies provide faster transient

response and allow the use of a smaller inductor. An

external compensation pin provides flexibility in setting

frequency compensation, allowing the use of low ESR

small ceramic output capacitors.

Features

• 4.0A, low r

integrated low-side MOSFET

DS(ON)

• +2.3V to +6.0V operating input voltage range

• V operating range: 1.1 * V to 24V

OUT

• 640kHz or 1.22MHz switching frequency

• High efficiency: 93% for 5V , 12V

at 0.5A

OUT

• Adjustable soft-start

• Internal thermal protection

• 0.8mm maximum height 10 Ld TDFN package

• Pb-free (RoHS compliant)

When in shutdown mode, the ISL78219 draws current at

<1µA and can operate at as low as 2.3V input. These

features, along with higher switching frequency, allow

use of tiny external components and minimize the overall

PCB footprint.

• Halogen free

• AEC-Q100 Grade 2: -40°C to +105°C

The ISL78219 is available in a 10 Ld TDFN package

with a maximum height of 0.8mm. The device is offered

for AEC-Q100 Grade 2 operation with an ambient

temperature range of -40°C to +105°C.

Applications

• Satellite camera systems

• Auxiliary cooling fans

• Antenna and microphone supplies
