Manufacturer:IR Description:The MAX1536 constant-off-time, pulse-width-modulated (PWM) step-down DC-to-DC converter is ideal for use in +5.0V and +3.3V to low voltages for notebook and sub- notebook computers. The MAX1536 features an internal PMOS power switch and internal synchronous rectifica- tion for high efficiency and reduced component count. No external Schottky diode is required across the internal synchronous rectifier switch. The internal 54m PMOS power switch and 47m NMOS synchronous-rectifier switch easily deliver continuous load currents up to 3.6A. The MAX1536 produces dynamically adjustable output voltages for chipsets and graphics processor cores using a logic-level control signal. The MAX1536 achieves effi- ciencies as high as 96%. The MAX1536 uses a unique current-mode, constant-off- time, PWM control scheme. It has selectable Idle ModeTM to maintain high efficiency during light-load operation, or fixed-PWM mode for low output ripple. The programmable constant-off-time architecture allows a wide range of switching frequencies up to 1.4MHz, opti- mizing performance trade-offs between efficiency, output switching noise, component size, and cost. The MAX1536 features a digital soft-start to limit surge cur- rents during startup, a 100% duty-cycle mode for low- dropout operation, and a low-power shutdown mode that disconnects the input from the output and reduces supply current below 1µA. The MAX1536 is available in a 28-pin thin QFN package with an exposed backside pad. |
