ISL78201AVEZ Product details

The ISL78201 is an AEC-Q100 qualified 40V, 2.5A synchronous
buck or boost buck controller with a high-side MOSFET and
low-side driver integrated. In buck mode, the ISL78201 supports
a wide input range of 3V to 40V. In boost-buck mode, the input
range can be extended down to 2.5V and output regulation can be
maintained when VIN drops below VOUT, enabling sensitive
electronics to remain on during cold-cranking and start-stop
applications.
The ISL78201 has a flexible selection of operation modes
including forced PWM mode and an optional switch to PFM mode
for light loads. In PFM mode, the quiescent input current is as low
as 300µA and can be further reduced to 180µA with AUXVCC
connected to VOUT under 12V VIN and 5V VOUT application. The
load boundary between PFM and PWM can be programmed to
cover wide applications.

Features
• Buck Mode: input voltage range 3V to 40V (refer to “Input
Voltage” on page 15 for more details)
• Boost mode expands operating input voltage lower than 2.5V
(refer to “Input Voltage” on page 15 for more details)
• Selectable forced PWM mode or PFM mode
• 300µA IC quiescent current (PFM, no load); 180µA input
quiescent current (PFM, no load, VOUT tied to AUXVCC)
• Less than 5µA (MAX) shutdown input current (IC disabled)
• Operational topologies
- Synchronous buck
- Non-synchronous buck
- Two stage boost buck
- Non-inverting single inductor buck boost
• Programmable frequency from 200kHz - 2.2MHz and
frequency synchronization capability
• ±1% Tight voltage regulation accuracy
• Reliable cycle-by-cycle overcurrent protection
- Temperature compensated current sense
- Programmable OC limit
- Frequency foldback and hiccup mode protection
• 20 Ld HTSSOP package
• AEC-Q100 qualified
• Pb-free (RoHS compliant)

Applications
• Automotive applications
• General purpose power regulator
• 24V Bus power
• Battery power
• Embedded processor and I/O supplies
