Ordering number: EN7258 Monolithic Linear IC LA5636M DC/DC Converter Secondary Side Control IC Overview The LA5636M is a DC/DC Converter Secondary Side Control IC that draws power from a car battery and is ideal for use in rechargers for lithium ion batteries, etc. Because this IC incorporates only the basic functions (constant voltage control and constant current control) that are needed in an IC for charging, it can be easily used in combination with other ICs for charging. Package Dimensions unit: mm 3086B [3086B] 10 6 0.63 1.7max 4.4 0.15 (0.5) 5.0 Includes integrated circuitry for preventing the malfunction of the system in the event that the input voltage (car battery voltage) drops. Produces constant voltage output in proportion to the PWM input signal. (Permits output voltage control by microcontroller.) High-precision reference current (current control amp): 92.5 A±2.7% Output voltage can be set through an external resistor. Each loop of the voltage amp and current amp is independent. 1 5 0.35 1.0 0.1 (1.5) SANYO: MFP-10S(225mil) Specifications Maximum Ratings at Ta = 25°C Parameter Supply voltage Allowable power dissipation DOUT terminal current/voltage PWM input voltage ICONST terminal voltage C1 terminal voltage Operating temperature Performance garanteed temperature Storage temperature Symbol VCC max Pd max Idtmax/Vdtmax Vpwm VICONST VC1 Topr1 Topr2 Tstg Conditions Ratings 14.5 350 1/ –0.2 to VCC –0.2 to 3.0 –0.2 to VCC –0.2 to VCC –40 to +85 –25 ……
