I. Device Description
A. General
The MAX8546 is a voltage-mode pulse-width-modulated (PWM), step-down DC-DC controller ideal for a variety of
cost-sensitive applications. It drives low-cost N-channel MOSFETs for both the high-side switch and synchronous
rectifier, and require no external current-sense resistor. This device can supply output voltages as low as 0.8V.
The MAX8546 successfully meets the quality and reliability standards required of all Maxim products. In addition,

VI. .......Reliability Evaluation
IV. .......Die Information
The MAX8546 has a wide 2.7V to 28V input range, and does not need any additional bias voltage. The output voltage
can be precisely regulated from 0.8V to 0.83 x V
IN
. This devices can provide efficiency up to 95%. Lossless short-
circuit and current-limit protection is provided by monitoring the RDS(ON) of the low-side MOSFET. The MAX8546
has a current-limit threshold of 165mV. The device features foldback-current capability to minimize power dissipation
under short-circuit condition. Pulling the COMP/EN pin low with an open-collector or low-capacitance, open-drain
device can shut down the device.
The MAX8546 operates at 300kHz. The MAX8546 is compatible with low-cost aluminum electrolytic capacitors. Input
undervoltage lockout prevents proper operation under power-sag operations to prevent external MOSFETs from
overheating. Internal soft-start is included to reduce inrush current. This device is offered in space-saving 10-pin
μMAX packages.
