Product Description

DESCRIPTION:

• The MAX8732A/MAX8733A/MAX8734A dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems.
• The MAX8732A/MAX8733A/MAX8734A include two pulse-width modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V.
• These devices feature two linear regulators providing 5V and 3.3V always-on out- puts. Each linear regulator provides up to 100mA output current with automatic linear-regulator bootstrapping to
  the main SMPS outputs.
• The MAX8732A/MAX8733A/MAX8734A include on-board power-up sequencing, a power-good (PGOOD) output, digital soft-start, and internal soft-stop output discharge that prevents negative voltages on shutdown. Additionally, the outputs are high impedance when VCC falls below its UVLO set point while the outputs are enabled.
