Description of LM46001PWPR
The LM46001 regulator is an easy-to-use synchronous step-down DC-DC
converter capable of driving up to 1 A of load current from an
input voltage ranging from 3.5 V to 60 V. The LM46001 provides
exceptional efficiency, output accuracy, and dropout voltage in a
very small solution size. An extended family is available in 0.5-A
and 2-A load current options in pin-to-pin compatible packages.
Peakcurrent-mode control is employed to achieve simple control loop
compensation and cycle-by-cycle current limiting. Optional features
such as programmable switching frequency, synchronization,
power-good flag, precision enable, internal soft start, extendable
soft start, and tracking provide a flexible and easy-touse platform
for a wide range of applications. Discontinuous conduction and
automatic frequency reduction at light loads improve light-load
efficiency. The family requires few external components and pin
arrangement allows simple, optimum PCB layout.
Protection features include thermal shutdown, VCC undervoltage
lockout, cycle-by-cycle current limit, and output short-circuit
protection. The LM46001 device is available in the 16-lead HTSSOP
package (PWP, 6.6 mm × 5.1 mm × 1.2 mm) with 0.65-mm lead pitch.
The device is pin-to-pin compatible with LM46000, LM46002, LM43603,
LM43602, LM43601, and LM43600
